Because of the protective packaging from the mint, these coins all arrive in phenomenal condition. Each Silver coin is made from 1 oz of .999 fine Silver.
Each Silver coin in this series is struck within a strictly limited minting period (August 2017 - March 2018), making each coin exclusive and ensuring low mintages. Final mintage numbers are currently unknown.
