<p>[QUOTE=&quot;Jim-P, post: 6368788, member: 118020&quot;]I was collecting coins bigtime in the early &#039;90s.&nbsp; Bought a lot from dealers in one of the national coin magazines.&nbsp; Many of the coins I bought came in flips.&nbsp; And I bought a package of flips for other coins in my collection.&nbsp; Come to find out many years later that the flips are putting a green tint on my coins, most around the rim but some on the faces.&nbsp; So I&#039;ve been spending a few hours each day lately doing the acetone and new holders thing.</p><p><br /></p><p>Makes one wonder if these national coin dealers in the early &#039;90s knew that what they were using and selling were harmful.&nbsp; I don&#039;t remember any advice given with the coins, like after inspection transfer the coins into non-reactive holders, although I found some with interesting packaging: a paper envelope within the flip.&nbsp; Has anyone seen coin dealers do this?&nbsp; If I had known at the time I could have transferred the coin into the holder until I got proper holders rather than leave it in the PVC flip.</p><p><br /></p><p>[ATTACH=full]1252092[/ATTACH] [ATTACH=full]1252093[/ATTACH] </p><p><br /></p><p>So I&#039;m gradually working my way through my half-dollar three-ring binder.&nbsp; I get to some 1964 Kennedys.&nbsp; They look like they have a green tint like the Franklins I&#039;ve been doing.&nbsp; But the Kennedys aren&#039;t in the usual flips, they are sealed so the coins cannot be removed.</p><p>[ATTACH=full]1252098[/ATTACH] </p><p>[ATTACH=full]1252096[/ATTACH] </p><p>So I cut it open and drop the coin in the acetone bowl.&nbsp; Couple minutes later I try to move it and the coin is stuck to the bowl.&nbsp; Come to find out in addition to being in a flip the coins are encased, like in a PVC or silicone sleeve.</p><p>&nbsp;</p><p>[ATTACH=full]1252103[/ATTACH] </p><p>Looks so nice that it could be chromed plastic, but this is how it came out of the acetone bath.&nbsp; Weighs 12 g on my non-decimal scale.&nbsp; This next one is out of the flip but not yet bathed in acetone.[ATTACH=full]1252104[/ATTACH] </p><p>I bought these in the early &#039;90s so I suspect these are not Airtite brand containers or similar that are in use today.&nbsp; Has anyone else had coins encased in soft plastic like this?&nbsp; Did you keep them intact or re-holder them?</p><p><br /></p><p>Thanks,</p><p>Jim[/QUOTE]</p><p><br /></p>
