<p>[QUOTE=&quot;Kentucky, post: 1308661, member: 33176&quot;]<b>Cleaning (Gasp) of Coins</b></p><p><br /></p><p>It was interesting to see mention of a freeze/peel method. I searched it on Google and came up with this: <a href="http://www.dirtyoldcoins.com/restore/cointypes.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.dirtyoldcoins.com/restore/cointypes.html" rel="nofollow">http://www.dirtyoldcoins.com/restore/cointypes.html</a> Apparently used on ancient coins that have a REAL coat of grunge on them and which coins are never going to be considered MS60 coins, but the collector would like to attribute them. Essentially there are actually two different methods. The first method consists of freezing the coins in a freezer and then throwing them into boiling water. The metal will contract at the low temperature of the freezer and the fast heating will possibly cause the metal to expand faster than the grunge and cause it to crack. The Elmer&#039;s glue technique I have also seen for cleaning old nasty records. A thin film of Elmer&#039;s (or some white) glue is applied to the item being cleaned and the glue is allowed to dry. The dry glue is peeled off, removing anything that is loose and removable. No wiping or buffing here, so no polish lines, however the peeled glue would probably leave many surfaces quite porous (check out on youtube what it does to a nasty old LP record though). As far as &quot;re-surfacing&quot; the steel pennies, I have seen lots of ads where they have replated and thn polished the coins. Not sure how you would do this, although I have silver plated some New York subway tokens - but that is another story.[/QUOTE]</p><p><br /></p>
