My thought was acid damage as well. John1  |

I want to say acid but the letters one cent I think would be more eaten. I don't know how they would still be that sharp with 2/3s of the coin eaten away by acid.

Cujohn - You've stated my thoughts on this aspect also. I don't understand how the planchet can be so thin and the devices still have any relief.

My initial thought is that it isn't an acid-damaged cent either. I can see evidence of an intact rim, but yet this piece is smaller in diameter than the real coin.

looks like a pickle jar coin to me. eaten away by a light acid over a long period of time. the story goes that people put them in substandard pickles at seedy saloons using the oxidized copper to keep the pickles green.
an undersized planchet would not have struck up so well in the middle.

So, slow and mild acid exposure? Interesting.

Acid exposure does not account for the reduction in diameter and thickness while the features are mostly preserved. I'm going with game token or something more nefarious.

Acid coin.
I bought a coin labeled as wrong planchet awhile back, and I too thought it was an error at first.

@ hondo borguss - the idea behind the details being preserved despite the coin being eroded away is similar to how nic-a-date works on Buffalo nickels. basically the pressure from striking the coin creates slightly different densities of metal that have slightly different responses to being eroded away. with a light acid and a long time frame you can end up with some cool results. you could create one for yourself if you wanted. get a common Wheat cent or a dateless buffalo or something and put it in a dish of vinegar. flip the coin over regularly to get even results. its going to take months/years. |

 Acid is a logical assumption. |

The design, as stated above, does transfer into the coin metal to an amazing depth. This is my 1924-d buffalo that basically split in half after it was struck. The obverse is normal and the reverse design can still be seen even the mintmark, halfway into the coin.   |
