cannons New Member United States 2 Posts	Posted 08/29/2022 6:10 pm Ran across a 100% blackened Millard Fillmore Presidential dollar Coin in an old coin jar. Any pointers as to what may have caused this or if it indicates that it may not be copper? I suspect some weirdo might've sharpied it out. The first picture shows the intense black it is with the naked eye in natural lighting. In the last two pictures, I was able to get it to catch enough light so you can see through the blackness better. Any ideas? Report this Post to the Staff

cannons New Member United States 2 Posts	Posted 08/29/2022 9:47 pm My best scale is for cooking and is extremely inaccurate at low weights but it measures somewhere between 5 and 10 grams, closer to 5 than 10. I agree that it's likely damage in circulation, probably heat, but still very cool. If anybody has better answers or other suggestions let me know! Report this Post to the Staff
Sap Moderator Australia 16816 Posts	Posted 08/30/2022 12:48 am "Environmental damage" of some kind. Golden dollars are, effectively, made of a kind of brass. And brass normally turns black as it ages. So in a few hundred years, everybody's Presidential dollars are probably going to look like this. Yours, however, has turned this colour prematurely. Heat is one explanation; an adverse chemical environment (such as salt water or a chlorinated pool) is another explanation. It's not likely to be deliberate damage. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
