I've bought some air-tites for my coins but after learning more about acids, etc.... I'm wondering if anyone can confirm that they're archival and won't cause the coins to tone badly...
I believe airtites to be the absolute best. This thread raises a question in me. How do the capsules used by the US Mint compare to airtites?
The "foam" rings are made out of "Volara"... Thanks for the thread. Now I know what that stuff is called.
They are basically the same, but made by a different company. And before you ask, no I have never been able to find out specifically which company.
