1 oz. 99.99% Pure Gold Coin Maple $50 – GML (Bullion) – Royal Canadian Mint

With more than 25 million troy ounces sold since their introduction in 1979. The GML was also the first bullion coin to achieve the heightened standard of 9999 purity.

All 1-ounce 99.99% pure GML bullion coins dated 2023 will have three unique features for enhanced security—radial lines, a micro-engraved maple leaf and Bullion DNA^TM Anti-Counterfeiting Technology.

Enhanced Security

Bullion DNA^TM Anti-Counterfeiting Technology is an industry first that goes above and beyond coin authentication like no other. Every die used to produce GML coins is laser micro-engraved with an anti-counterfeiting security mark. Our registration process—digital non-destructive activation (DNA) technology—captures images encrypted with an algorithm signature, and stores these in our secure database. This proprietary Bullion DNA^TM technology facilitates the authentication of Gold Maple Leaf coins dated 2014 and later.

In 2013, the Mint introduced a new and unique security feature to confirm the authenticity of its GML coins. Derived from the same award-winning security technology applied to Canada’s $1 and $2 circulation coins, the GML security feature consists of a textured maple leaf, micro-engraved with laser technology on a small area of the reverse side of the coin. In the centre of this mark, visible under magnification, is the numeral year, denoting the coin’s year of issue.

The obverse features the effigy of Queen Elizabeth II by Susanna Blunt. The obverse also bears a special marking that includes four pearls symbolizing the four effigies that have graced Canadian coins and the double date of her reign.
