Buy a 1991 Britannia 1oz Gold Proof

This 1991 one ounce gold proof Britannia is one of the scarcest issues in the entire series, with just 143 examples struck in this individual presentation. Containing one troy ounce of 22-carat gold, this premium coin continues the tradition of featuring Philip Nathan's iconic 'standing Britannia' design on the reverse: a powerful depiction of the warrior queen holding a shield, trident and olive branch. The obverse bears Raphael Maklouf's third definitive portrait of Queen Elizabeth II, used on UK coinage between 1985 and 1997. With such a low mintage, this is a rare opportunity to acquire one of the most sought-after early Britannia proofs. Supplied in its original Royal Mint presentation case, complete with individually numbered certificate of authenticity.
