This rare 1983 Coat of Arms £1 pound coin features an interesting mint error where the design is upside down. The design includes the Coat of Arms of the United Kingdom, with the Latin inscription "DECUS ET TUTAMEN" below, which translates to "An ornament and a safeguard". This coin is a great addition to any collection, especially for those interested in British decimal coinage. The denomination of this coin is One Pound.
