Coining press

A coining press is a manually operated machine that mints coins from planchets. After centuries it was replaced by more modern machines.
Presses came in multiple shapes and with different accessories (to collect the coins, etc.) They were made of cast iron. The basic elements are:
Operation.
Each coin is formed in a single operation. The press holds two "negatives" (molds that show each side of the coin) The body (material from which the coin is to be formed) is placed on the lower negative and the upper negative is lowered to create pressure sufficient to emboss the negatives onto the body. The upper negative descends directly without turning, pushed by a threaded bar that rotates, turned by a lever, compensated by an anti-torsion system. It is called a cold deformation as not heat is applied.
History.
Before the press, coins were minted with a hammer:
