help identify composition of this coin

[buffhunter]

got this coin today while searching rolls of halves. it is a 1960 CINCUENTA CENTAVOS, from the REPUBLICA DE COLOMBIA. On the obverse, it says LIBERTADOR SIMON BOLIVAR. I would like to know what the coin is made of. I have looked, but cant find any sites saying the composition.

Sweet find.

Copper-nickel alloy.

Coins of the same design struck from 1912 to 1933 were 90% silver, however.

copra nickle mix (copper & nickle ) --once it gets a bit of age on it often looks and seems to be silver but its not.

so sorry coincrazed --- its clearly marked 1960 * and is a cincuenta (50) centavo (cent) piece--- between 1952 and 1958 the silver content of these coins the 10 , 20 and 50 centavo were changed over to cupro - nickle alloy --- thus this metal blend was used and once it get a bit of age on it this metal blend "looks" just like old silver does.

being its past 1958 (being its a 1960 dated coin -- its cupro nickle)
