Is it better to store these in a box with little-to-no air flow and desiccants? (Those little "do-not-eat" packages)
Is a dry environment best or is a bit of moisture better?
Thanks!
Ideally, a climate controlled environment is best. I use an airtight box for unslabbed/ungraded coins, and yes I use dessicant packages as well, just to be safe. Metals and moisture are a bad thing IMO
