The Principality of Seborga consists of about 14 square kilometers on the Italian Riviera near France. It became a Principality in 1079. In 1729 it was sold to the King of Sardinia. Unfortunately someone forgot to do the paperwork so the change was never officially registered with the Kingdom of Sardinia.  Seborga was not mentioned in the Act of Unification of Italy or subsequent acts, thus it still considers itself independent. It has its own flag, coins, stamps, passports, and automobile license plates. In 1995 and 1996 it issued its first and only coins since the 17th century.  The mintages of all the coins were limited and are now quite difficult to obtain.
