I did a search for coin storage and didn't find a specific answer to my question, so here goes:

I'm looking for a means to preserve my bullion coins (silver eagles, maples, etc) so as to prevent tarnishing, corrosion, etc. I currently have them in PVC-Free Airtites stored in a cardboard box along with some 3M anti-tarnish strips. I just bought a FreeSaver vacuum sealer along with some of the plastic containers. So, I'm thinking of vacuum sealing my coins, in their air-tite containers, for ultimate preservation.

One of my containers has a 7 in the triangle, which is a polycarbonate (BPA). An another of my containers has "SAN" in the triangle, which is Styrene Acrylonitrile.

My questions: Will either of these damage my silver? Are they flawed like PVC plastic? (Reminder: they're not in direct contact with the coins)

Thanks for any responses!

P.S. I know this is probably overkill, but it's how I do most things. lol
