Non-ferrous coin blanks

It has worked out historically that circulation coins in any country reflected the level of state economic stability. First coins were made of precious metals but later they were changed to non-ferrous metals due to the same application properties for much less cost. Production of non-ferrous coins of small denomination is unprofitable for any economics as the metal cost exceeds face value. Still, usage of non-ferrous metals for circulation coins is explained by several reasons:

- Coins are the symbol of state credibility and reflection of stable economic situation;

- In case of emergency available non-ferrous metals can be easily remelted into defence products – cartridge and shell cases.

Bicolor blanks are used for circulation coins of the highest denomination and jubilee coins. As a result of production, they possess contrast colors of rings and cores. To illustrate this type of coins, we may mention 1 Euro coin, 2 Euro coin and 10 Ruble coin produced from various compositions of copper and nickel.

· CuNi25;

· CuNi19 (substitute for CuNi25 due to 8% price reduce);
