Looks like the plating was stripped or the zinc was ever plated to start with.

Ahhh, I take back my earlier statement. I was confused at which one you wanted examined. In this case, I agree with Tim. Interesting find!

It does seem to be unplated, although understand that it is not hard at all to remove the zinc overlay at home. I don't think it is "normal" wear. Is the reverse the same?

I will bet the copper cent was zinc plated. This is a common middle grade or high school chemistry class experiment. http://www.stevespanglerscience.com...gold-penniesIf you stop in the middle of the experiment it is a silver zinc color, if you continue with the heat , you can get a gold cent. Thousands are made every school year and put back into circulation when the novelty wears off. Jim |

Have you weighed it? Fire maybe?

Dull rough surfaces are almost always due to post-mint plating removal. Unplated planchets can only be authenticated in a nice high AU/MS condition with luster remaining- that is the key point. Post-mint removal of the plating will strip the coin of luster. Genuine unplated planchets will also have a natural silvery-blue color from the zinc. Authentication also creates another problem though. A genuine unplated planchet that has seen circulation and environmental exposure will also undergo significant oxidation of the zinc, resulting in a coin that appears to have been altered  |

well the coin weights the 2.5 grams. So basically biokemist6 there is no way to tell what this coin is then?

If you look close you can see the shadows of copper.
This coin was a normal zincoln that either through deliberate
or environmental issues lost it's copper.
