The 2019 2oz Gold Una and the Lion Proof Coin was the first release in The Royal Mint's modern Great Engravers Collection and remains one of the most important premium Royal Mint issues of the modern era. Struck from two troy ounces of 999.9 fine gold, it revives William Wyon's celebrated Una and the Lion design with modern proof minting standards. As the launch coin for the series and one of the most sought-after Great Engravers releases, it carries a very strong collector premium within BT.
