1/2 Dollar - Roy I Orca

Sealand's claim to sovereignty rests on a 1968 ruling by a British court that the former Royal Navy sea fort HM Fort Roughs — sitting just outside UK territorial waters — fell beyond British jurisdiction. Roy Bates declared it a principality that same year. The coins it has issued since the 1990s carry no legal tender status anywhere and were produced purely as novelty revenue, sold rather than circulated.

The two catalog variants (X#8.1 and X#8.2) differ in minor die details.
