Seeker_101 Pillar of the Community United States 1791 Posts	Posted 05/03/2025 12:49 pm I read vinegar would remove rust and so put the coin in vinegar. After a bit life happened and the coin was left in the vinegar for a long time so I guess it would be considered cleaned now. Here are the before and after photos. Report this Post to the Staff

sel_69l Bedrock of the Community Australia 21786 Posts	Posted 05/04/2025 12:22 am Like verdigris on copper, brass and bronze coins, rust on steel coins permanently damages the surface. Much better to try to look for steel coins with unblemished surfaces. Such coins can be quite scarce. Report this Post to the Staff
