Hi All,

My internet searches have turned up empty so I hope my fellow collectors can help. I'm looking for tips and information to protect my collection. At the moment, I own about 40 high grade vintage cards (1957-1967) all in PSA holders. Lately, I have grown more and more concerned about preserving them over the long haul. I currently store them all in two stackable Sterlite plastic boxes. I know sunlight is a killer but what else should I be concerned about? Does the PSA slab offer any protection? Do the PSA slab rails damage the card? Any help would be much appreciated.

Thanks,
