That is probably because there are few rules that would apply to all cleaned coins. There are different types of cleaning, a coin that has been dipped in chemicals versus one that has been whizzed versus one that has had ultrasonic cleaning will all have different diagnostic markers. Plus, some cleaned coins have been artificially re-toned.</p><p>Your best bet is to have patience and learn the process through experience, by looking at a lot of coins. This is how most (if not all) of us here have learned to tell the difference.[/QUOTE]</p><p><br /></p>
