Instead of CuNiZn like previous years (KM#56 and KM#40) these new types' composition is Multilayer material: low carbon steel core electrochemically coated with a layer of copper on both sides, electroplated with a layer of copper and finally with a layer of brass.
Weight is now 5.78 grams instead of previous 6.13 grams.
