Challange Coin

Solid brass or high-density zinc alloy foundations, precise engraving, hand-applied challange coin, and unique edge-milling options like diamond-cut, rope, or reeded finishes are needed to create 3D sculpted or high-relief die-struck challenge coins. To guaranty long-term tarnish resistance and structural weight uniformity, every production batch is subjected to stringent neutral salt spray corrosion testing and plating density verification.
