Banknote denomination code

A 20 ice mark note issued by the Central Bank of Westarctica has a number of security features and each note has a unique serial number printed on its front in two places. This serial number unique identifier, which is composed of for elements which are separated by hyphens. The first number is a four-digit number that indicates the denomination of the note. All four spaces in this number must be occupied: the value itself will be right-aligned, and any unused spaces are filled with the number zero. Thus, a 20 ice mark note always has a serial number that begins with 0020.

Note serial number

Next comes a set of alphanumeric codes corresponding to that bill’s unique serial number within its denomination series year and issue year, and is separated from the next two elements by a hyphen (-). It always contains eight numerical digits, and may or may not be followed by a letter.

Possible note serial letter code

If any two notes end up for any reason carrying the same note serial number, then this set of numbers will be immediately followed by a letter indicating the note belongs to a different set of series numbers; since note series numbers are not issued sequentially and do not correspond to any "order of printing" of such notes, the number of possible series numbers does not need to be exhausted in order for a serial number letter code to be needed on a note.

Serial year codes

Following the second block number is one (or more than one) digit corresponding to the serial year that the bill was first issued (though not the calendar number of that year itself)— for example, the first 20 ice mark note issued in 2019 (the first series year for the 20 ice mark note) will have an Arabic numeral 1 here, as will all other 20 ice mark notes issued in 2020, 2021, 2022, etc. However, if a new distinct series is created in any subsequent year (which could be 2019, 2020, 2030, or any year number), then that series will be coded with the next higher number in the sequence (i.e., 2, 3, etc.). There is no upper limit to this number. All bills within a given serial year will have the same basic visual format (arrangement of elements, use of colors and emblems) as other notes of that serial year, regardless of when that note was actually printed. If there is a major revision of a bill at a later date, this will invoke a new serial year code rather than simply a new series code (see below). The serial year code will always be followed by a hyphen.

Series code

Following the serial year is a final letter block indicating the note’s series code for that series year. This letter (or, potentially, letters, typically A-Z) corresponds to a minor variation for that note within its series year, and may be arbitrarily and non-sequentially chosen within the 26-letter Roman alphabet. All notes that follow the format and appearance of the original series year will have the same letter code(s) in this field; if the Bank of Westarctica decides to issue a different kind of note within the same series year, then that note will bear a different letter(s) here. Only if more than 26 such series letters become necessary for a given series year will the field contain two letters (e.g., “FR” or “AG” or any other two-letter code). There is no upper limit to the length of the series code which a note may bear, so long as each series note is identical in all aspects of its appearance (other than its serial number) to other notes in the same series year and can be clearly differentiated from other notes in different series. The series code does not indicate the note’s series year or printing year, though certain series years will only bear certain series codes (which means a series year may sometimes be deduced backwards from an apparent series code). All bills must have a series code, even if the appearance of that note never varies (in which case all such notes issued for that series year would have the same single- or double-letter series code letter).

Examples

A bill whose QR code reveals its serial number to be 0020-34992322C-4-Y indicates that this is a 20 ice mark note, note number 34992322, which, by virtue of the letter “C” at the end, means this note happens to be one of at least two notes with this particular serial number that was issued within some serial year, here indicated by the number 4 (the fourth serial year for the 20 ice mark note, the fourth time this note has seen a major new design— let us say that the Bank of Westarctica decided to issue newly designed 20-ice-mark notes in 2018, 2020, 2023, 2030. Then the 20-ice mark note which was largely redesigned in 2030 would be coded with the number 4, followed by ss series letter, in this case “E”, which only means that thisnote is somehow different from any other bill bearing the letter “A” or “H” or any other code in this field (but is not considered different enough to qualify for a different series number).

Another example: A note whose serial number is 12237770-1-3-AZ indicates that this note, number 12237770 (no other notes from this serial year or printing year bear this same serial number because there is no letter following the 0 at the end), matches the design of similar bills originally printed in that same series year (which, because it is a 1, must be 2018 but was actually printed in 2021 (the numeral 3 means that this bill was printed in 2018+3=2021, and that this note’s appearance is essentially the same as the 2018 note) and is the “AZ” series bill printed that year (meaning that there must have been at least 26 other series bills also printed that year for that series year, though this field does not tell the user additional information nor if more than 52 such series notes were eventually printed for that series year and print year).

Third example: A note with the code indicating 00030020A-2-4-WEX. This indicates that the note holds the serial number 00030030 and was the second note to bear that serial number for series year (because the first note with that number did not have the letter A at the end) and was printed in the style of the 2018 note plus... ...Two years, =2020, meaning this note was the for the issue year was 2020, and was... ...the 4th design for that bill that year of issue, and... ...belongs to the WEX series of bills issued that year and in the format of 2018 (?)

-Sandbox text for 20 ice mark note:
-It was decided on August 8, 2018 by decree of His Royal Highness and following a discussion by members of the Royal Council to name the paper currency of Westarctica “ice marks”, and all subsequent issue of Westarctican paper currency shall be understood to be in denominations of ice marks regardless of whether or not said currency actually bears the English words “ice marks” or any variation of this term or any equivalent or similar term appearing in any language.
-The ice mark is established as a whole-number decimal unit of currency.  According to this system, there are no units of currency less than one ice mark as well as no fractional units of ice mark.
+==Banknote denomination code==
+A 20 ice mark note issued by the Central Bank of Westarctica has a number of security features and each note has a unique serial number printed on its front in two places.  This serial number unique identifier, which is composed of for elements which are separated by hyphens.  The first number is a four-digit number that indicates the denomination of the note.  All four spaces in this number must be occupied: the value itself will be right-aligned, and any unused spaces are filled with the number zero.  Thus, a 20 ice mark note always has a serial number that begins with '''0020'''.

+==Note serial number==
-===Relation to the Westarctican dollar===
+Next comes a set of alphanumeric codes corresponding to that bill’s unique serial number ''within its denomination series year and issue year'', and is separated from the next two elements by a hyphen (-). It always contains eight numerical digits, and may or may not be followed by a letter.
-Westarctica’s paper currency is entirely separate and independent from and has no correspondence to Westarctica’s system and concept of cryptocurrency, [[WestarcticaCoin]], or to the Westarctica dollar coins.  These forms of currency are not interchangeable or exchangeable, and other than being under the control of the government of Westarctica bear no formal relation to each other.
-===Backing===
+===Possible note serial letter code===
-As of 2018 and unless or until indicated otherwise, Westarctican paper banknotes have no backing in specie and may not be redeemed within Westarctica or elsewhere for any form of bullion.  Neither are these notes tied to any existing exchange rate with regard to other forms of currency, whether micronational or other, anywhere in the world.  However, they are available as items of curiosity; other entities may offer exchange rates for these notes at whatever rate they deem appropriate, if any.  With regard to the current (2018) issue of banknotes and until/ unless other subsequent notification is given, Westarctica takes no interest in such matters.
+If any two notes end up for any reason carrying the same note serial number, then this set of numbers will be immediately followed by a letter indicating the note belongs to a different set of series numbers; since note series numbers are not issued sequentially and do not correspond to any "order of printing" of such notes, the number of possible series numbers does not need to be exhausted in order for a serial number letter code to be needed on a note.
-Also note that the bearer of any Westarctican banknote of the extant series of such banknotes may not demand redemption of these notes for any amount of currency issued by any micronational nor non-micronational government entity.  Unless indicated otherwise, banknotes issued by the Bank of Westarctica do not have any exchange value with regard to any published exchange rate of any world currency, past, present, or future, and the holders of said banknotes shall not expect said currency to be recognized as holding intrinsic comparable value in the currency of any nation.
+==Serial year codes==
+Following the second block number is one (or more than one) digit corresponding to the serial year that the bill was first issued (though not the calendar number of that year itself)— for example, the first 20 ice mark note issued in 2019 (the first series year for the 20 ice mark note) will have an Arabic numeral 1 here, as will ''all other 20 ice mark notes issued in 2020, 2021, 2022, etc.''  However, if a new distinct series is created in ''any'' subsequent year (which could be 2019, 2020, 2030, or any year number), then ''that'' series will be coded with the next higher number in the sequence (i.e., 2, 3, etc.). There is no upper limit to this number. All bills within a given serial year will have the same basic visual format (arrangement of elements, use of colors and emblems) as other notes of that serial year, regardless of when that note was actually printed. If there is a major revision of a bill at a later date, this will invoke a new serial year code rather than simply a new series code (see below). The serial year code will always be followed by a hyphen.
-==Terms==
+==Series code==
+Following the serial year is a final letter block indicating the note’s series code for that series year. This letter (or, potentially, letters, typically A-Z) corresponds to a minor variation for that note within its series year, and may be arbitrarily and non-sequentially chosen within the 26-letter Roman alphabet. All notes that follow the format and appearance of the original series year will have the same letter code(s) in this field; if the Bank of Westarctica decides to issue a different kind of note within the same series year, then that note will bear a different letter(s) here. Only if more than 26 such series letters become necessary for a given series year will the field contain two letters (e.g., “FR” or “AG” or any other two-letter code). There is no upper limit to the length of the series code which a note may bear, so long as each series note is identical in all aspects of its appearance (other than its serial number) to other notes in the same series year and can be clearly differentiated from other notes in different series. The series code does not indicate the note’s series year or printing year, though certain series years will only bear certain series codes (which means a series year may sometimes be deduced backwards from an apparent series code). All bills must have a series code, even if the appearance of that note never varies (in which case all such notes issued for that series year would have the same single- or double-letter series code letter).
-On its obverse side Westarctican paper currency bears a QR code.  This code corresponds to the note's serial information, which will be unique to that note.  The serial information of each note includes more than a unique number, it also contains information about the issue of the note.  The components of this information include the following parts, each separated from the others by a hyphen in a single line:
+==Examples==
+A bill whose QR code reveals its serial number to be 0020-34992322C-4-Y indicates that this is a 20 ice mark note, note number 34992322, which, by virtue of the letter “C” at the end, means this note happens to be one of at least two notes with this particular serial number that was issued within some serial year, here indicated by the number 4 (the fourth serial year for the 20 ice mark note, the fourth time this note has seen a major new design— let us say that the Bank of Westarctica decided to issue newly designed 20-ice-mark notes in 2018, 2020, 2023, 2030. Then the 20-ice mark note which was largely redesigned in 2030 would be coded with the number 4, followed by ss series letter, in this case “E”, which only means that thisnote is somehow different from any other bill bearing the letter “A” or “H” or any other code in this field (but is not considered different enough to qualify for a different series number).
-*“Denomination code” - this [usually four digit] number code corresponds to the denomination of the banknote on which it appears, with placeholder zeros for any note whose value us under 1000, aligned to the right.  The code for a 20 ice mark note, for example, is 0020; a 100 ice mark note would be 0100; a 5,000 ice mark note would have the number 5000.  Any banknote issued with a denomination above 9,999 ice marks would simply have more digits in it, with no upper limit to the possible value of this code.
-*“Serial style” - this number corresponds to the overall visual appearance at the time of creation of a give banknote of a given denomination, regardless of year it was actually printed, and is coded by a sequential number beginning with 1, indicating the first overall style of printing for that denomination: all notes whose designs are essentially the same as the ''original'' note for that denomination, for example, will bear the number 1. In a second style is printed 10 years in the future, it will be coded with the number 2.  If a third style is printed that same year, it will have the number 3.   This number has no upper limit, and is always sequential.  All 20 ice mark notes currently in existence have a number 1.  If a different style is eventually produced, this has a number 2, but if the original style of note is for some reason subsequent to this, the serial style will revert back to 1 again.  If a new style of note is issued subsequent to ''this'', that note will bear the number 3 (indicating that it is the third style of note for the 20 ice mark denomination).
+Another example: A note whose serial number is 12237770-1-3-AZ indicates that this note, number 12237770 (no other notes from this serial year or printing year bear this same serial number because there is no letter following the 0 at the end), matches the design of similar bills originally printed in that same series year (which, because it is a 1, must be 2018 but was actually printed in 2021 (the numeral 3 means that this bill was printed in 2018+3=2021, and that this note’s appearance is essentially the same as the 2018 note) and is the “AZ” series bill printed that year (meaning that there must have been at least 26 other series bills also printed that year for that series year, though this field does not tell the user additional information nor if more than 52 such series notes were eventually printed for that series year and print year).
-*“Printing/ Issue year” - this number is equal to numerical difference between the year that a note of a certain denomination was printed and the year that this denomination of note was first ever printed.  All notes issued/ printed in the same year that the note's denomination came out will have a value of zero in this position.  The year that any note was actually printed can always be established by determining the first year that any note of that denomnination was issued and adding the value of this piece of serial information to that year.  This number takes no account of the serial style value, which is independent of it.  A 20 ice mark note printed in 2020 will have a value of 2 (the first year of printing of any note of this denonination having been 2018).
+Third example: A note with the code indicating 00030020A-2-4-WEX. This indicates that the note holds the serial number 00030030 and was the second note to bear that serial number for series year (because the first note with that number did not have the letter A at the end) and was printed in the style of the 2018 note plus... ...Two years, =2020, meaning this note was the for the issue year was 2020, and was... ...the 4th design for that bill that year of issue, and... ...belongs to the WEX series of bills issued that year and in the format of 2018 (?) Note (?)
-*“Serial number” - this six-digit number is unique to each banknote for a given denonination, serial style, and printing/ issue year.  Should all six digits be used up or otherwise become designated as unavailable, a suffix letter may be added to this number to indicate an additional banknote with that same six digit numerical code (and of the same denomination, and the same style, and with the same year of issue) has also been printed and to differentiate it from that note.  The following letters are never used in any part of the serial information of any Westarctican banknote because of their superficial resemblance to Arabic numerals: the letters '''O''', '''I''', '''S''', and '''Z'''.
-*“Series code/ letter” - this is an arbitrary single-character alphabetic code to indicate a minor variation in note format for a given denomination with a given overall style and with the same printing year.  It is unrelated by the bill’s serial number, though some serial codes may only correspond historically to certain serial numbers.  All banknotes will bear a series code, even if the serial year and printing year had no minor variations.
-==Features of the 20 Ice Mark note==
-The Central Bank of Wesarctica, embodied in His Royal Highness the Grand Duke, is the sole producer of legal tender Westarctica currency in banknote or specie.  The 20 “ice mark” note (the currency symbol for which is the U+2745 tight trifoliate snowflake in the Dingbats Unicode block which somewhat resembles a 6-fold symmetrical snowflake) began printing in 2018.  It is the first official bill printed by the monarchy since the nation’s inception.  Like all banknotes, the Westarctican 20 ice mark banknote has an obverse and a reverse.  This document describes the various decorative and security features of both sides of the 2018 printing.
-===Obverse===
-The obverse of the 2018 20 ice mark banknote features a portrait of the reigning Grand Duke, [[Grand Duke Travis]].  This image appears on the note’s left side and has been rendered in an engraved format.
-To the portrait’s direct right are a series of orange [https://en.wikipedia.org/wiki/EURion_constellation EUR+ion] constellations intended as an anti-counterfeit measure.
-Across the top appear the words “Twenty Westarctican Ice Marks”, the denomination of the note written in English.
-To the left of this is a guilloche symbol situated behind the numbers "2" and "0" along with the unicode symbol for the ice mark (as outlined above).  The guilloche medallion appears behind the Grand Duke's head, while the numbers "2" and "0" are placed before his head.
-Along the left side of the note is a dark strip announcing that the note has been issued by the “Central Bank of Westarctica”.
-In the bottom center of the note, below the written statement indicating the denomination of the note, appear the words, “This note is legal tender for all debts within Westarctica”.
-In the bottom center of the bill appears a scanable [https://en.wikipedia.org/wiki/QR_code QR code] graphic.  This QR code corresponds to the bills unique serial information, <-- which is composed of 3 elements which are separated by hyphens.-->  If scanned, the code will allow the user to access the bill’s alphanumeric serial code along with any other relvant information about the bill.  This code will appear in the following format:
-Signature of the Grand Duke
-	Each bill contains an officially recognized copy of the signature of the Grand Duke.
-Lesser coat of arms
-	The lesser coat of arms appears on each note, in an engraved format.
-Lower right 20
-	The number “20" on the lower right of the bill has a background in guilloche patterns
