Mylar flips in PVC files

Hello fellow collectors!  I  have a question  for  you. If I  put  coins in Mylar flips and then in PVC pages will that  still damage the  coin even if it  is in the flip. I am forced to do this as I only   need  2 extra pages for my album and its not worth paying a whole new  set. Let me know if its safe doing this method and regards!

Good question!

The Mylar flips are PVC free, and are accepted for long term storage of coins. However they are not 100% sealable or air tight from my experience, to then place them in PVC pages could in theory leave the coins open to any chemical reaction from the PVC. But the coins wouldn’t be in direct contact, and the slots in the PVC pages may actually help compress the Mylar flips so that they are 100% air tight… 🤔

I would say that nobody here would disagree with the idea, and that those who store coins in a similar manner haven’t had any problems over the short term. I personally don’t store my coins in either, so only have experience from dismantling others collections from PVC or flips, sometimes removing flips easily from PVC pages is a pain and I often slice the pages up with a knife, so if you are not fussed about removing the flips on a regular basis go for it.

I just storage my coins the same way, Mylar flips are safe. 

The common deterioration of coins in Mylar flips it's a reaction to the acids/dirt already attached to the coins.

My experience with UNC coins it's that they remain perfect!
