[QUOTE="Insider, post: 7520500, member: 24314"]In case you missed this Numismatic News article: My New Year’s resolution is in the form of a confession to collectors everywhere who are reading this column. I confess to being a coin doctor. Err what? Yes, I alter the appearance of any coin I’m asked to conserve. In my defense, I like to think it makes them more attractive and preserves them for future generations; but technically they have been changed using either chemical, mechanical, or a combination of techniques to alter their appearance. You might be surprised to learn that there are a large number of us in the community of collectors. Have you ever “dipped” a coin to remove haze? So why do the words “coin doctor” carry such a bad connotation? Easy, it’s because there are “good” coin doctors and those who are not so good both in their level of expertise and especially in their intentions. Why is the alteration being done?
