10 centesimi - Giorgio I

Seborga's claim to independence rests on a 1729 transaction it argues was legally defective, leaving the village technically outside the Kingdom of Sardinia and, by extension, never formally incorporated into unified Italy. Giorgio Carbone, a flower farmer elected "Prince Giorgio I" by local referendum in 1963, leveraged this argument to issue coins, passports, and stamps — none recognized by Rome. The luigino, Seborga's self-declared currency unit, was priced at an absurd 6 USD by decree.

Carbone died in 2009. The principality continues under elected successors, though Italy has never acknowledged the sovereignty claim in any legal forum.
