MikeBI recently bought a large safe. Approximately 800 lbs. The problem is that most safes are rated for 1200 degrees for 30-90 minutes. This is about the same as the small safes you can buy at Target. In a fire, the inside of the safe should not exceed 375 degrees. I was told that paper burns at 405 degrees. However I believe that the plastic cases would laminate your cards at 375. There are safes rated at much higher numbers, but they are very pricey. I have put a small safe in the large safe, hoping that the combination will keep the slabbed cards safe.
