Heres a perfect example of what a Copper coated zinc cent looks like for any of you that would be interrested in seeing.Found this one in a piggy bank my mother started for my son. While upgrading his piggy back . ot cracking it open like a coin pheen on the hunt. Natesdad
looks like some of the cents that I find at the beach,with my metal detector, after only a short term in salt water and sand.
yes the level of damage that happens are very much the same. Salt will wreck almost every metal on earth over even just a short time.
Except for gold. I have found gold rings lost in the 1940's and they look like they were dropped yesterday.
