<p>[QUOTE=&quot;Kentucky, post: 4999131, member: 33176&quot;]I don&#039;t trust hydrogen peroxide on coins.&nbsp; Hydrogen peroxide is an oxidizer that can cause a coin to...duh...oxidize.&nbsp; Acetone isn&#039;t that bad.&nbsp; I would put some acetone in a container that will hold the dollar and allow it to be totally immersed.&nbsp; Cover it and let it sit overnight or longer.&nbsp; I fish it out with my fingers and blot it with a tissue or toilet paper.&nbsp; You can replace the acetone and repeat if you think it helps.&nbsp; My next move would to put it on a cloth in a sink and let very hot water from the tap run over it for 1/2 - 2 minutes, turn it over and repeat.&nbsp; Rinse with distilled water and see if it helped.&nbsp; None of the above should damage it.[/QUOTE]</p><p><br /></p>
