<p>[QUOTE="Ken Dorney, post: 2996850, member: 76086"]A good question. Since various ink manufacturers likely use different formulas (and consider that most inks are produced in China) there likely is no way to know what will happen in the long term. Ink usually reacts with plasticized flips in about 10-20 years or so (sometimes sooner). I just received a coin this morning stored in such a flip for about 20 years. Hopefully you can see the reaction in the ink in this photo:</p><p><br /></p><p>[ATTACH=full]740562[/ATTACH] </p><p><br /></p><p>As a double pocket flip it wasnt in contact with the coin of course, but the coin was indeed in contact with the flip. Some may have experienced where the coin will begin turning green and take on a 'sticky' feel to the surfaces. This one was no different but a quick swipe with water and cloth fixed it up nicely. Moral of the story, plasticized flips are just fine for short term storage and for shipping by dealers, but they should be replaced with non-PVC safety flips:</p><p><br /></p><p>[ATTACH=full]740563[/ATTACH][/QUOTE]</p><p><br /></p>
