Extremely rare celtic coin punch from the 3rd century BC with associated electron stater coin of the Sequani (from Switzerland - France area, see photo). Material electron, gold with a high silver content. The punch is made of iron with significant signs of wear from the stamping. There are slightly conical depressions on each side from inserting a coin blank. This was then punched with a countermark. The embossed finished coin was then knocked out (see hewn edges on the edge of the stamp, clearly visible). The two-sided possibility for embossing on this punch, made possible a faster and more efficient use and production of the precious coins of that time. In the centre of the punch head there is a square recess, where there are remains of wood (petrified, hard with iron baked). Presumably there was a handle was attached, similar to a hammer, with the help of which the punch was not fixed but flexible. Very important document piece of Celtic coinage. Museum condition.
