Nickels and Clad coins have a bit of copper mixed in the nickel.. hence Cupro-Nickel. When exposed to chemicals or the elements it tones the copper.
Nickels and clad coins have a bit of Nickel mixed in with the Copper.. hence Cupro-Nickel. 75% copper & 25% nickel.
If you are going to go all in, clad coins are net 88% 12% because they are two layers of 75-25 surrounding a 100% copper core.
Yes, that is true. 88%. All our silver colored coins are mostly copper and our copper colored one is not .
Nickels are 75% copper but they are nickel colored. It's an alloy, the copper never shows through. Which is why 99%+ of copper colored nickels are rusted/ environmentally damaged. Once in a blue moon you will get a Black Beauty, (improperly annealed planchet) but that is not really copper colored. And even rarer, is if you get a nickel struck on a copper cent planchet. But those aside, there aren't any copper colored nickels.
