Sap Moderator Australia 16837 Posts	Posted 01/30/2010 05:52 am Hi, alfredm, and welcome to the forum. Sad to say, but I think your coins will be beyond repair. Fire-damaged bronze coins rarely can be recovered to a collectable condition - the fire has usually "burnt" the coins themselves, creating a thick layer of black copper oxide that can't be removed without giving the coins a "cleaned" appearance. First, use soap and water to wash off the ash, dirt and loose stuff. Then you could try the "usual" harsh cleaning techniques, such as household acid (lemon juice or vinegar) buffered with salt. But be warned, you'll probably end up with coins that are worth not much more than scrap metal value, whatever you do. 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

Just use scrubbing as a last resort because it will leave straight line scratches that will make almost as ugly as they are now, only cleaner. Where are my manners? to the forum.
