Which die/hub usually carries the reeding pattern during silver panda coin minting? Is it the die/hub for the obverse or reverse, or is the reeding pattern stamped independently, maybe by the holder/receptacle in which the blank is inserted for stamping? Thanks for clarification because I don't know the answer. Best wishes.
In order to hold the coin securely during the striking process, a metal collar that is the exact diameter of the coin is placed in between the two coin dies. A planchet is placed on top of the anvil die and held securely by the collar.
The collar has a series of small grooves already carved into it. When the planchet is struck at tremendous pressure, the coin tries to expand out the side but is held in place by the collar. The tiny grooves on the collar are now transferred to the edge of the coin.
