The Republic of Palau is an island country in the western Pacific, in free association with the United States. In one way or another, the country has been under US administration since it was established, and has never had its own separate currency - it has always used the US Dollar. However, Palau allows some foreign mints to issue coins under its authority; these are denominated in US Dollars but are only legal tender in Palau, so can in a way be considered to be in "Palau Dollars", even though such a currency does not officially exist.
The coins are usually dedicated to historical or general popular culture themes not related to the country itself. Many of them are in standard bullion sizes, including the internationally popular one troy ounce of silver.
The Mint says about this coin:
Sharks, at least some of them, are animals you don’t want to get bitten by. The bite marks are in the coin and it is bent. A unique new technology and something totally new in coin design.
Well-known species such as the great white shark, tiger shark, blue shark, mako shark, and the hammerhead shark are apex predators-organisms at the top of their underwater food chain. Many shark populations are threatened by human activities. |
