Gold Proof 1980 Sovereign Boxed

This Mint 1980 box-set features a single gold Proof Sovereign coin. This coin weighs the same as a regular sovereign, at 7.98grams and 22-carat gold (91.67% fineness). This proof has been struck using specially selected blanks and highly polished dies. During striking, the coinage dies exert enormous pressure on the coin blank, with at least two separate blows (or strikes), ensuring that the impression has extra clarity. Complete with its own booklet, and bound in a good looking green leather case.
