25 Cents - Roy I Orca

Sealand — the former Royal Navy anti-aircraft platform Roughs Tower, seized by Paddy Roy Bates in 1967 and declared a sovereign principality — has issued coins intermittently since the 1970s, none of which have ever functioned as genuine circulating currency. This piece dates to the early 1990s, when a wave of such "fantasy" issues flooded the novelty and bullion markets. The X# prefix in the catalog reference confirms its non-circulating status outright.

Roy Bates died in 2012; his son Michael has administered the platform since.
