<p>[QUOTE="Just Carl, post: 551875, member: 4552"]Now here is something we never thought about. A hugh data base of fingerprints so we could trace who put it there. Imagine a Lincoln Cent with Lincoln's finger print on it? Or a Buffalo Nickel with the Indian's finger print on it that posed for that coins obverse. And how much would a Kennedy Half be worth with his finger print on it? :smile<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p>First of all what is the value of the coin? How recent is it date wise? If relatively new, no much value, it may have been a recent fingerprint. If so it may come off easily. If it's been there for a while, might be to late. Since everone's body is different in chemical makeup, the amount of acid in thier sweat is different. This means that some fingerprints are so acidic that even a few days will make it permanent. In some instances it's basically only an oil that leaves that print and it would come off with Acetone. </p><p>An example of this is at a coin show I purchased a 1995 Lincoln Double Die Cent in possilby MS-65 for practically nothing. Had a massive fingerprint on the obverse. At home I tried Acetone, then Laquer thinner. Nothing. So with little to loose I dumped it in one of those jars of jewlery cleaner from Walmart. Left it there for several hours. Removed it and the fingerprint was completely gone. May or may not work with other fingerprints and other coins.
