<p>[QUOTE="Just Carl, post: 568959, member: 4552"]Not all fingerprints will leave the same chemicals and not all of the ones they do leave will have the same effect on different metals, coins. Ever notice how some people can probably run a marathon with very little sweat and some people start sweating crossing the street? Some fingerprints contain strong to weak acids, different oils and salts. Since people's body chemistry is so different, the results of touching a coin can have excessively different results as well as how long they are left in place. And what you eat could also make differences in your sweat so what you leave on a coin's suface can vary extensively. I've seen coins with a finger print so obvious, it could be seen several feet from the coin. </p><p>This should indicate that if a coin is to be considered a collectable, keep your fingers off. Many have found a pair of cotton gloves are the easiest and safest method to handle coins. </p><p>Of course if your uncertain about the handling of coins, you could just send all yours to me and I'll handle them properly for you. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" />:goofer:[/QUOTE]</p><p><br /></p>
