10 Dollars Fiat - G91Y

The Marshall Islands began issuing collector-oriented legal tender coinage in the late 1980s through a licensing arrangement with the private firm Medallic Art Company, producing brass and clad pieces in quantities driven entirely by collector demand rather than any domestic monetary need. The $10 denomination was never intended to circulate — the islands' functional currency has always been the US dollar.

KM#239 is one of dozens of themed issues the RMI released throughout the 1990s, a program that drew sustained criticism from numismatic bodies for blurring the line between coins and medals.
