How incuse coins are made
Incuse coins are created the same way that traditional coins are made: two dies strike a planchet surrounded by a collar. The difference between conventional coinage and incuse issues is in the creation of the dies.
The traditional dies have recessed design details so that the design devices of the coin are raised on the coin, whereas dies for incused coins need to be raised and realized in higher relief to “punch” the details below the fields of the coin.
The higher the definition, the higher a relief treatment on the dies is necessary to achieve a detailed design on incused coinage. The increased definition may require more force in the striking process and precision in setting up the coin press to result in a well-struck incused coin with full design details.
