Janvier Machine

The Janvier transfer reducing machine traces a larger than actual coin design from a galvano or epoxy shell unto the end of a piece of steel which will become the master hub. The resulting design on the master hub is the actual diameter of the coin and in raised relief just as it will appear on the coin.
