Gold - Britannia - 1oz Proof

The one-ounce Gold Britannia Proof series began with the programme's first collector issue in 1987. Each coin contains one troy ounce of fine gold and uses specially prepared dies and polished blanks, with the alloy changing from 22 carat to 999.9 fine gold in 2013. Annual artistic interpretations of Britannia create a varied proof date run.
