:loud:This is a worse case scenario of course, but I used it because it really hits home on a high grade better date like this. Look and learn, vinyl flips are bad, bad, bad. I puchased a bunch-o-Lincolns last month, several with bad damage like this. They sat for long term without being looked in on. No amount of olive oil, acetone, koinsolve, nothing I know short of a dremel and a wire brush will help. I tried 2 weeks in olive oil then acetone.....zero results While this person ruined a run of 1910-s thru 1915-s coins, all this grade, no 14-D thank God, we can learn from their heart ache. Ouch huh? edited - there's a line that can't be crossed Jack I'll start a biggest ouch of the year contest with this one.
I'm afraid I could show you many Spanish coins from the XVII to XX th centuries with great "ouch"-es like that. I can't understand why numismatic shops do not tell buyers the risk of using them.
I didn't relize the flips where that bad, I mean I thought they where fine for short term storage and put some of the new presidential dollars in flips. I noticed in a matter of weeks they where covered in PVC. WEEKS! I thought it took long term exposure like years! That was eye opening to me, now whenever I buy a coin that is in a flip it immediately gets an acetone bath no matter what - Maybe I should have always done this but live and learn.
That's odd for sure. I've been putting coins of all sorts in 2x2's for as long as they've been around. Possibly for many, many years. Some coins have been in them for possibly 20 years. No problems at all. I use different brands, some are 1-1/2 x 1-1/2 and most are 2x2's. I've used plastic rolls, albums of most brands, coins in jars, cans, boxes and no problems like that at all. Whatever attacked those coins may be worse than you think. I would suspect there is another problem in the area where such coins have been stored. If I were you I would carefully inspect the area since there may be some type of gasses or other problems present. I also doubt it is PVC. However, anything is possible.
not all flips/plastics are made with polyvynilchloride. some use other plasticizers. always use mylar flips to store coins in. they contain no dangerous plasticizers, slip additives, surface coatings, antioxidants, or use acidic-hydrolysis.
This is what I was told. I bought 1 coin, then was told there was a whole collection available but some had some damage, they had to go along with the set, which was stored since the 70's as it was left. They did not say, garage, closet, etc. I bought everything as a whole. Some were pristine, many were toned in old Whitman and Library of Coins albums, and a bunch of tubes and 2x2's. It is unfortunate because the " better dates " were probably seperated from the rest and put into flips because they were more valuable. The albums had lower end vg/fines in the semikey holes, and they are still no problem coins.
This is not always a smart idea. Just examine the coin, if there is PVC you'll see it. Otherwise, leave it alone.
