Abstract (en)
[origin: WO2013127405A1] Coins consisting of a steel core and a nickel surface layer are internationally known, as are coins with a copper surface layer. In circulating coins, nickel remains shiny, while copper becomes dull and dark, whereby the coin loses aesthetic appeal. In contrast to nickel, however, copper has antimicrobial properties. The objective is to provide a coin blank from which a coin can be stamped that permanently retains its shine and also has antimicrobial properties. The coin blank according to the invention consists of a core made of an iron material (1) with a surface layer (2) made of nickel which has ultra-finely dispersed doping (3), preferably consisting of copper, on and near the surface.
