The 10EURO German collector coin AUF DEM WASSER “On the water” consists of a copper-nickel core, a blue niobium-coated copper-nickel ring and a translucent (clear) polymer (plastic) ring infused between the two metal elements.
Weight: 9,8g
Diameter: 28,75mm Conditions: BU and proof Year Mark: 2021 Mint workshops: “A” (Berlin), “D” (Munich), “F” (Stuttgart), “G” (Karlsruhe) and “J” (Hamburg).
Edge: smooth and without any inscription (Core: 81% Cu+19% Ni
Transparent Polymer Ring Outer Ring: 97%Cu+2,5%Zn+0,5%Sn, Niobium plating)
Germany issued coins with clear plastic polymer ring. During the development of this coin, the selected plastic is resistant to temperature changes, the humidity does not damage the quality of the coin, and the polymer ring does not react when exposed to UV radiation or chemicals.
Niobium is a chemical element with chemical symbol Nb (formerly columbium, Cb) and atomic number 41. It is a light grey, crystalline, and ductile transition metal. Pure niobium has a Mohs hardness rating similar to pure titanium, and it has similar ductility to iron. Niobium oxidizes in Earth's atmosphere very slowly, hence its application in jewelry as a hypoallergenic alternative to nickel.
