it depends on what item it is
It depends on when it was made and whether or not it is in good working condition. Most likely it is. You could also sell it for parts.
no it can kill you it is too dangerous its worth nothing unless you want to die
Nickel silver is a copper alloy...60% copper, 20% nickel, and 20% zinc. The name comes from its color and appearance. So....it is worth more as scrap metal than as a "precious metal". Sorry!
