<p>[QUOTE=&quot;Flying Joe, post: 43405, member: 2555&quot;]<b>Same here - 30 years of PVC</b></p><p><br /></p><p>As a child in the &#039;60s, I collected pretty complete sets of Canadian coins, getting many from my Mother and Grandmother.&nbsp;&nbsp; Thanks to my family&nbsp; - it is quite a collection - although all the coins are circulated many are at least 100 years old and have some value.</p><p><br /></p><p>And yes, Sigh... <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" /> , I stored them all in lovely soft clear plastic pages which were in a binder.&nbsp; 30 years later, I pull out the binder and am interested in continuing collecting finally, and of course everything is very very green.</p><p><br /></p><p>From the sounds of it from other posts and this one, I will essentially have to wash most of my coins in acetone.&nbsp; So, special ones, like my 1936 quarter with a raised dot, will get devalued in the process, but at least the damage will stop.&nbsp; I have many many pennies from the 1900s so for those I&#039;m hesitant to dip, but I guess I must for the silver.</p><p><br /></p><p>3 questions:</p><p>Oddly enough, some of the silver coins have no visible PVC greening effect on them, but others look like they&#039;re in a liquid almost.&nbsp; First: Can I skip dipping those with no visible greening?</p><p><br /></p><p>I also had some quite old paper currency as well in special folders in the same system.&nbsp; I guess I need to remove them from those pages too, but I guess there&#039;s nothing to stop potential damage from them being there already, I guess. Second:&nbsp; Is that right?</p><p><br /></p><p>Third: What happens when you place the coins in the dip for a minute?&nbsp; Does the green loosen up or come off?&nbsp; Should I use fresh acetone for each coin out of the many many dozen I must do this with?&nbsp; And I read after dipping for a minute, I will then rinse under the water tap and dry without rubbing - how?</p><p><br /></p><p>Thanks for your help[/QUOTE]</p><p><br /></p>
