250 Roubles Sikorsky Ilya Muromets

There is no Antarctic issuing authority with any legitimate monetary function — "Antarctica" coins are novelty issues produced for the collector market, typically licensed through private intermediaries and bearing no relationship to circulating currency. This piece honors the Sikorsky Ilya Muromets, the world's first four-engine aircraft, which flew in 1913 under Igor Sikorsky's direction in Saint Petersburg before the program was repurposed for heavy bombing runs by the Imperial Russian Air Service during World War I.
