 I found a 1907 Indian Head cent in a recent roll I purchased of mixed wheats and a few Indians. The coin is thinner than a regular Indian and is just slightly smaller in diameter--just enough to not hold itself in the hole in my Whitman folder. Otherwise, it looks like a normally struck coin. I am trying to charge up my old camera batteries to get pictures now. Sorry, I don't have a modern phone with a camera, only an old flip-phone. Until I get some pictures up, does anyone have any idea what it could be? A normal Indian Head weighs 3.0 grams. This coin weighs 1.9 grams. On closer inspection, the rim appears to be almost completely missing down to the inner marks of a normal rim's interior, yet it doesn't look shaved or abused and has a smooth edge. Thanks for any info, Shane Edited by dsburton

 to CCF. Need pics but sounds like PSD. Someone filed it down to make a coin to fit in a dime machine maybe. Just a thought. John1  |

Would use in a fuse box make a cent smaller and lighter? I've heard of people used to use cents this way.

Classic acid coin. Bummer man, poor coin probably had more than one bad trip by the looks of him.  |

Why would someone put in acid? Was that a method of cleaning or just someone having fun?

I have a IHC just like this, and a large cent. When I posted them, I got the same answer. Does a expert know what type of acid might have been used. And how long the coin might have been placed in the acid. If possible, I would like to try and recreate the process. With before and after pictures. Unless someone has already done this. I would even provide coins if someone is set up for such a test. |

There are probably several different acids that would work. How long it would take would depend on the acid and the concentration. It can even happen naturally. Oak and black walnut leaves are high in tannic acid. Run off from decaying leaves to a puddle withthe coin in it would do it eventually. Sanitary sewers are often high acid environments. Areas downwind from coal fired power plants tended to suffer from acid rain. In this case the acid being sulfuric. Standing water there could also do this. So you can't say for sure if it was deliberate or not.

most liquids have some acidic qualities, lots of common stuff, coke, or other sodas, lemon, orange and lime juices.
a 100+ year old coin has been in a few places it probably should not have been, and this is where it was exposed.

Phosphoric acid will achieve this result given enough time, as well as acetic acid or citric acid concentrated to a high strength, but sulfamic acid or sulfuric acid are more likely, both are common in liquid and gel dip/cleaner/polish type products. Hydrofluoric acid, too, if you're the dangerous type.

Honestly I don't think it is an acid coin. The US Mint was making coins for a number of foreign countries at this time. I think it is a planchet for a foreign coin.
Acid should have destroyed the devices. And not just the distal portion of the rim. I'm not a chemist but I am an Engineer.
