To clean or not to clean...

That IS the question. If you call any coin shop in the nation and say, "I've got a bunch of old coins, should I polish them up before I bring them in?", the coin dealer will undoubtedly tell you, NO! And in this case, I would agree. However, I am one of the few dealers / collectors that encourages collectors to learn HOW to clean coins.

A dealer once told me that he 'touches up' 75% of the coins that come through his door. Another dealer friend told me he spends a few hours a week 'reconditioning' his recent purchases, but he doesn't clean them. Well, call it what you will, but cleaning a coin is cleaning a coin. If you learn what you are doing, most dealers will not know that you even touched it. I've even heard a stroy from a dealer who cleaned a coin, sold it, and then bought it back not realizing until later that he had actually cleaned that exact coin!
