The Royal Canadian Mint's Bullion DNA Program Since 2015, the Bullion DNA program. Offered by the Royal Canadian Mint has provided the highest security on the market for any bullion coin. Each coin has its own unique textured security privy mark that has been micro-engraved with laser technology and can be seen only under magnification. Two numbers are etched into the security mark, creating a unique identifier for each product. The mint records, encodes and scans each micro-engraving for authentication, giving each coin its unique Bullion DNA.
