The coins are all heavier then these weights however, as they contain 22-carat (91.67%) gold.  The remaining alloy was copper (crown gold mix) until 1989, and is now Silver. These Proof sets are all boxed with individual certificates of authenticity. The One Ounce Silver Britannia and the One Ounce Gold Britannia are also available to purchase.
