Take a look at this video on Youtube http://www.youtube.com/watch?v=G_1k...ture=related It does work. Theirs other videos as well you can research and see what works, Many of the post's here are going to teach you a very valuable lesson. Don't clean your coins. I see theirs no talking you out of it so good luck. A great book on this subject by a very respected man is Coin Chemistry Master6238 are you left with a lot of hairlines, Samething with Tarnex I would think the rubbing would have to produce some. I'm not calling anyone out. Just figure theirs got to be some surface changes going on. |

Just spend it to get rid of it and buy another one, if it bothers you that much.
Or - a Dremel tool with a grinding wheel should remove those annoying spots. Warning - you may end up with a few hairlines.

Ill post a pic once I clean it. Haven't decided how to do it yet.
I do believe you can clean coins and preserve them, sometimes they are better off for it. the knee jerk reaction people have to cleaning coins really doesn't accomplish anything productive.
With that said; most coins will be worse for wear if you clean them improperly, and, yes, most coins shouldn't be cleaned. But, there are certain coins, if cleaned well that are better off for it.
I'm thinking of starting a new thread, maybe a dirty coin cleaning challenge sort of thing. I will picture one very dirty coin, Then after everyone offers their opinion on the best way to clean said coin, ill proceed and show the before and after results. Still in the works though so it won't be anytime soon.

I would try a quick dip in a liquid silver jewelry cleaner. I have had some good results doing this on some low value, higher quality coins for my collection. If you are going to keep the coin and add it to your collection, do what you want to with it. If someone cleans coins to enjoy in their own collection, so what. If someone cleans coins to deceive another person, then that is bad.

That is true but the most important point that most people miss is the fact that selecting the coin for improvement potential is the key detail. Many collectors have thought at one time or another that they could help a coin by cleaning it a little bit but therein lies the problem- the vast majority of collector-grade cleaned coins(read: problem coins) on the market were once cleaned by an owner who thought they were "improving" the coin. You cannot just "hope" that the coin's eye appeal will be improved, you have to know it will be improved before you even touch the coin. Experience is the only thing that will keep you from messing up coins by cleaning them but that experience is usually gained by also messing up alot of coins  |

I find it amusing that everyone says you shouldn't "clean coins" but so many people do it...and so many coins for sale are cleaned...I guess there is a right way and a wrong way to clean them....I just dont know it

polishing compound and a rag, rub like crazy Use the ones found in the auto aisles at most stores. Works on cars so why not on a coin? Quote:
Or maybe a hardened steel brush on a drill? No not a stell one, you have to use a Silver Wire Wheel on a Silver coin. If your really intent on cleaning that coin, try that jewlery cleaner sold at Walmart in the Jewlery department. Usually works but may make the coin turn colors later. So if you really do, rinse well with distilled water. |

Interesting topic. I just want to know how to undo someone else's damage.
Copper when its been cleaned looks just horrible. As an experiment on a low buck cleaned cent I applied heat. A small amount of heat produces some interesting rainbow toning. I would never pay the kind of money some of these shysters want for rainbow toned coins nor are they all that desirable. Once you see how a bit of heat or perhaps some chemical persuasion causes toning its all a ripoff.

Natural toning is defined by slow kinetics of the oxidation reaction. Applying heat or adding chemicals exponentially increases the kinetics of the reaction which does result in a different toning scheme. |
