Discovery and name
The island was mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos, 1959-65. Pranke Island was named for James B. Pranke, an aurora researcher at Byrd Station in 1965.
Pranke Island Coin
In 2011, the Central Bank of Westarctica minted bronze and bi-metallic $10 Westarctican Dollars Coins for Pranke Island. The mintage was 300 and they are especially unique due to their diamond (or square) shape, as opposed to the traditional round shape for a coin.
The coin shows an image of an emperor penguin chick.
