I have seen plenty of threads where the coin in question is identified as having been "cleaned". Even I have identified coins as being cleaned, as I can tell sometimes. Here's the questions I have on this subject. Oh, I didn't have an example coin I could use so I googled images and this was one of the best one's that came up and it could belong to someone on here I think, I hope they don't mind. Anyone? 1. Is a cleaned coin considered a problem coin to you? 2. If you have two coins that (appear) to both be MS64 and one is cleaned, how much percentage wise will the cleaned coin sell for? Speculation is fine as I'm just trying to get an idea. :kewl: 3. How bad is it to buy a cleaned coin? Your opinion or a linked opinion, whatever you want to use.
