<p>[QUOTE=&quot;Kentucky, post: 2859320, member: 33176&quot;]Wow, I opened the worm can...&nbsp; Copper coins are somewhat difficult to clean given the reactivity of copper.&nbsp; In the condition the coin is, it&#039;s not worth a bunch, but you would like to have a nicer looking coin.&nbsp; Let&#039;s start with some acetone or xylene if you have any.&nbsp; Soak the coin for an hour and see if the solvent gets any color, if so, change the solvent and give it another hour and repeat till the solvent is colorless.&nbsp; If you don&#039;t have any acetone or xylene, do water in the same way (distilled is best, but tap will work as long as you dry the coin off - pat, don&#039;t rub).&nbsp; You do seem to have some corrosion on there (the green spots) and we need to talk about them too, but get started with the water.&nbsp; If you are tempted to scrub it, don&#039;t use anything more abraisive than a toothbrush.[/QUOTE]</p><p><br /></p>
