Manufacture of Coins:
In the
manufacture of coins, a strip of metal having a precise thickness is fed into a
blanking press, upper left, which cuts planchets (or blank disks) of the
required diameter. Next, the planchets are softened and cleaned in an annealing
machine. The upsetter smoothes and thickens the edge before the coin is washed,
dried, and stamped. The stamped coins are then inspected, counted, and bagged.
A weight check is performed on each bag of coins before it is shipped.
