Action to strike, by means of a press, a Blank between two Corner S to obtain a currency.

Technologies of striking evolved/moved much in order to adapt to the needs increasing for the money circulation and the requirements for quality:

• the Striking with the hammer: the coiner struck with the hammer a mobile corner which printed its mark on the blank, initially posed a fixed corner. The irregular contour of the currencies was the product of manual cutting to the chisel of the blanks on the metal plate.

• the Striking with the beam, tested under Henri II, was generalized by Jean Warin, in 1640, for the current production of the currencies. The press was ordered by an arm ballasted of two weights at the two ends ordered horizontally with the hand. The movement of the press to the bottom was led by a slide to screw, with a constant angle.

• the Striking with the lever: after the invention of a press driven by the vapor according to the process invented by Watt about 1790, the monetary press of Uhlhorn, invented in 1817 substituted for the pressure of the screw of the beam that exerted by a lever. The press of Thonnelier, installed in Paris in 1833, was driven by the vapor and took as a starting point the process of the lever. The modern presses, like that installed in Pessac, are computerized and automated.

The progression of the outputs of striking at the minute is considerable from one technology to another:
