[QUOTE="GDJMSP, post: 1396157, member: 112"]Yes, the dipped copper will start toning again immediately. This is a little experiment I did for different reasons. This is a copper coin immediately after being dipped in Tarn-X - [ATTACH]167391.vB[/ATTACH] This is the very same coin just 3 days later - [ATTACH]167392.vB[/ATTACH] The area to the right around the date was also rubbed with a pencil eraser, that's why it did not tone the same. And no, Tarn-X is not what you would use if you were trying to turn a copper coin red again. But even when using something that harsh, you can still see what happens and how fast it happens. Now imagine if you did it the right way. And then you stored the coin properly to maintain the red color. It really is not difficult for people with knowledge. This the coin after 43 days -[/QUOTE]
