[QUOTE="bgarg, post: 212550, member: 1876"]I know that most of you will say "Never clean a coin". So, I don't "clean" my copper coins. I preserve them. Mostly I use a coin cleaner by name "Coin Care" for my copper coins. It does an amazing job on old copper coins. It removes the organic stuff from coin but doesn't touch the original patina and color of copper coins. Even after few years, I haven't seen any change in the color of those preserved copper coins. Mostly I have used this cleaner on not very expensive coins. I know a local collector who uses this cleaner on some high end coins and then get them graded by top TPGs. Also, while attending Long Beach Show, I met few dealers who exclusively deal in early large cent and half cent coins. And I have seen them using this same cleaner on their coins worth thousands of dollars. After seeing them, it gave me little extra confidence for using this cleaner on some of mine which needed preservation. Note: I am just sharing my experience regarding preserving copper coins and am not advocating anything specific. Also, I am not linked with the company in any way which produce this chemical.
