Storage of Graded Cards -- Advice?

[clydepepper]

I would recommend a fire-proof safe. When I think of what can harm cardboard and plastic, the first thing I think of is fire.

I keep 72 (all that will fit: 61 PSA & 11 SGC) highest dollar graded cards in my Sentry safe, about 700 post-war, pre-standard sized cards in a locked wooden Dakota safe - taking a little chance with the fire threat, but at least they are fairly well secured.

Still another wooden box (no lock ) contains 500 pre-standard cards (1956 set and 160 of 1955 set).

I have 14 binders containing my Topps 1957-1976 years and everything else is in regular cardboard storage boxes, usually 900 or 5000 each.

I don't have any floods or hurricanes where I live, but heat can bring fire, so be careful out there.
