A one-armed ejection lever of a coining press is adapted to be controlled in one end section directly by the coining ram by way of a connecting rod and in the other end section by an operating piston-cylinder unit. The center portion of the ejection lever is placed by way of a pressure bolt against the projecting end of an ejection rod. The abutment pressure is produced by the operating piston-cylinder unit whereby the ejection coining die is able to yield by way of the ejection rod, for example, in case two pieces to be coined are in the coining tool in order to avoid damages. For multiple coining, it is additionally possible to act upon the operating piston cylinder unit in the opposite direction and to effect therewith an intentional lifting-off of the pressure bolt from the ejection rod.
