<p>[QUOTE=&quot;desertgem, post: 8230855, member: 15199&quot;]They are your coins. Many respected people have carved them up due&nbsp; to being bored and later having excellent collecting /selling value, some have made them into jewelry and ignored any damage such as punching a center hole to make rings, some have (due to cultures) included them as wedding belts, some threw silver dollars to the air to shoot holes in them, some put them into milk to purify it. Most people would be happy receiving or purchasing some of these, but &quot;cleaning&quot; as a numismatic term is poorly defined as to severity and more often defined by intentions, which doesn&#039;t make sense chemically. Some solutions such as pure acetone ( except for the micro-quantity of horrible tasting, vomiting producing chemicals to stop you from drinking it ) does not affect copper, silver, gold, iron, etc. under conditions a human could survive.&nbsp; </p><p><br /></p><p>The CDC has this about acetone.</p><p><a href="https://wonder.cdc.gov/wonder/prevguid/p0000467/p0000467.asp#head004000000000000" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://wonder.cdc.gov/wonder/prevguid/p0000467/p0000467.asp#head004000000000000" rel="nofollow">https://wonder.cdc.gov/wonder/prevguid/p0000467/p0000467.asp#head004000000000000</a></p><p><br /></p><p>Even the great and cautious&nbsp; state of California allows you to buy gallons if you are an adult.</p><p><br /></p><p>It does not react or dissolve metallic coin materials by the<span style="color: #ff0000"> vast majority</span> of chemists. so it can remove&nbsp; dried&nbsp; secretions , common garbage and dirt, <span style="color: #ff0000">fresh</span> fingerprints and not by itself damage the coins. Use of applicators though CAN cause scratching both visible and microscopic. Microscopic scratches can make the coin shine, but a grader can easily recognize the action. So dips and soaks can help &quot;clean&quot; coins and not leave any evidence or damage. Coinage made from ceramic or plastic ( such as older tax tokens coinage).&nbsp; &nbsp; IMO, Jim[/QUOTE]</p><p><br /></p>
