COIN MINTING PROCESSES - A GRAPHICAL REPRESENTATION


Here is the  image  which indicates various basic processes during minting of coins , it would give idea how the sequence of processes taking place from start to end .




During  manufacturing 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 smooths 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.
