MINTSHIELD™ Surface Protection

MINTSHIELD™ from the Royal Canadian Mint is the world's first and only proven solution for reducing white spots on silver bullion coins — a proprietary advancement developed by the innovative minds at the Royal Canadian Mint and applied to every Silver Maple Leaf bullion coin dated 2018 or later.

Tackling a persistent problem

White spots — also known as "milk spots" — on silver bullion coins have been a concern for investors and mints around the world for years. While they in no way alter precious metal content, they do affect a coin's aesthetic appeal. In its commitment to produce the highest-quality bullion coins possible, the Royal Canadian Mint resolved to solve the white spot challenge.

Scientifically proven protection

The Mint subjected Silver Maple Leaf bullion coins to a wide array of advanced scientific tests and diagnostic procedures, identifying the root causes of white spots and developing MINTSHIELD, a unique production process, to prevent them. Invisible to the eye and having no impact on the coins' quality or precious metal value, MINTSHIELD is proven to significantly reduce the appearance of white spots for years.
