It's very important to have in the title. * Cleaning out my late aunt's house and found this in a tub full of match books. Could prolonged exposure to the sulfur have blackened this coin? From what I can tell it isn't worth much more than scrape. Would it hurt any value to clean it? Edited by Doug G 10/08/2023 6:53 pm Report this Post to the Staff

kbbpll Pillar of the Community United States 4233 Posts	Posted 10/08/2023 12:09 am I wonder what a long soak in pure acetone would do. It can't hurt to try. Who knows, maybe prolonged exposure to soot from a coal furnace was also the culprit. Report this Post to the Staff

Doug G New Member United States 3 Posts	Posted 10/09/2023 2:45 pm Coinfrog, I can't say. But I do not know of my aunt and uncle ever having a fire. I would think it would be blackened or melted partially. This is an even gray. Report this Post to the Staff
Sap Moderator Australia 16332 Posts	Posted 10/09/2023 9:12 pm Hello and welcome. This appearance could have several causes, but further speculation is unnecessary, since the culprit is named in the OP: Quote: ...found this in a tub full of match books... Yes, being sealed up in a confined space with a large amount of elemental sulfur (found in typical match-heads) will turn a silver coin black. If you'd like proof, simply get yourself a nice shiny silver coin, and seal it up in an airtight box with a bunch of matchbooks. Fresh matchbooks would be more potent, rather than your late aunt's decades-old matchbooks that have probably already lost a lot of their sulfur. A year or so should give an adequate demonstration. As for cleaning, it would be safe to say that if any dealer owned this coin, they would dip it in silver dip before selling it. Hopefully they would do the dipping in a well-ventilated place; this degree of blackness on a large coin like a dollar would emit quite a lot of hydrogen sulfide gas when dipped. 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
