1 Dollar - Roy I Reverse Strike

Sealand — the former Royal Navy sea fort HM Fort Roughs, seized by Paddy Roy Bates in 1967 — has issued coins intermittently since the 1970s, none of which have ever functioned as circulating currency. This 1994 bronze piece is a reverse strike, meaning the dies were applied inverted relative to standard orientation, a production anomaly that in Sealand's case almost certainly reflects the informal nature of its minting operation rather than any deliberate error coinage program.
