Abstract:
Coins, medals or casino tokens have a first side, a second side, at least one first layer made of a first material and at least one second layer made of a second material, wherein the first layer is between 10 μm and 90 μm, preferably 20 μm thick. A method produces the coin wherein the coin is produced, more particularly punched, from a clad sheet-shaped composite material. A further method produces the coin wherein the coin is formed from a ring and a core arranged inside the ring. The core and the ring are punched from a clad sheet-shaped composite material and subsequently the core is inserted rotated into the ring and is fixed therein.
