B.L.21 Posted May 27, 2019 Share Posted May 27, 2019 Hi guys...sorry if this is a dumb question...been searching a lot and it seems some type of flips are not great for long term keeping of a coin. I guess my question is, is it ok to keep coins in the, for years at a time? Or should you rotate into a new flip every once in a while? Link to post Share on other sites
Just Bob Posted May 28, 2019 Share Posted May 28, 2019 (edited) The ones that you want to be wary of are the kind that contain PVC, which can leach out and damage the coin. They can be recognized by their pliability, and their smell - they smell like a plastic shower curtain. Mylar flips are the safest kind. They are stiffer - almost brittle, but they will last a long time. I have some that have been holding the same coin for close to twenty years, with no adverse effects, and I am sure there are members who have had coins in the same flips for longer periods of time then mine. Not a dumb question, by the way. It was a good one, actually. Edited May 28, 2019 by Just Bob Link to post Share on other sites

If you are still not sure, ask at the coin shop where you buy them or check on the site where you get them. Bruce Link to post Share on other sites
JKK Posted May 28, 2019 Share Posted May 28, 2019 In practice, since I don't think there is any market any more for PVC-based plastics in contact with coins, what this means is taking a good look at the apparent age of the flips of coins you acquire. If there seems any possibility at all that they are PVC, replacing them is automatic and absolutely necessary. Flips are so cheap it's penny-wise and pound-foolish to let a great coin rot in a PVC flip. By the way, this also goes for tubes. I once had about forty PVC-deteriorating tubes of Jeffs and wheaties (think how many coins that is), which had left them all covered with disgusting green slime. Acetone will take it off, but for a while there they looked and felt like they had smurf mucous all over them. Definite drag. Link to post Share on other sites
Mokiechan Posted May 28, 2019 Share Posted May 28, 2019 I had a year set of Japanese Coins from their mint that were in a PVC holder, this was before it became well known how damaging they were. The coins all got coated with ugly green slime. Don't ever buy a Japanese Mint Set in packaging like this: Mohawk 1 Link to post Share on other sites
JKK Posted May 28, 2019 Share Posted May 28, 2019 That is seriously sad, Mokie. Basically, the packaging did a bushururu on the coins. Mohawk 1 Link to post Share on other sites

Mohawk Posted May 28, 2019 Share Posted May 28, 2019 (edited) I love Japanese coins, Mokie, and this is one of the saddest PVC victims I've seen on this forum........no one wants a Bushu-suru of any kind, but especially not on your coins!
