Copper blanks are used for minting coins and medals by stamping or engraving a custom design onto the blank. We supply other mints and manufacturers with these blanks and planchets so they can strike their own coins and medallions. Our customers comment on the quality of our blanks and how easy they are to stamp. In fact, a customer recently contacted us to trade our copper blanks for some that he purchased from one of our competitors. Our competitor’s copper blanks were too hard, and therefore could not be easily struck to impress their design.
Our copper blanks are made from pure .999 fine copper, known as Cu110. Other alloys are available and we recommend you call us to check availability and minimum quantities.
