Silver is a different animal. It's so soft that you can't use scrapers or brushes on it without scratching it up. Fortunately, silver stands up really well to many chemical treatments. You can try a hot peroxide bath to loosen the crud if it's organic. More likely the black stuff is tarnish, which forms when the silver reacts with sulfur in the soil. The process can be reversed with electrolysis. The simplest form of that is to put the coin in a bath of hot water, aluminum foil, baking soda and a little lemon juice. 1 2 Link to comment Share on other sites More sharing options...

Valens Legacy Posted October 22, 2023 Share Posted October 22, 2023 Great job on the back of the coin, looks like it came from a high end coin dealer. Good luck on your next hunt. 3 Link to comment Share on other sites More sharing options...
