A Sentry safe should only be for extra fire protection in my opinion. The ones with a simple key lock can be opened with a screwdriver. I had one that I broke the key partially off inside the lock and used to open it and close it with a penny! Any bigger sentry safe that I've seen can pretty quickly be opened up with a pry-bar as well. They're good for protecting low value stuff by themselves or paperwork, but for valuable cards I'd want them as an interior safe inside a large heavy duty safe. (By this I mean one that you won't find in any chain sporting goods or department store. Only store to look would be Cabelas or online from a major dealer. you want one probably a minimum of 6-700 pounds. Ideally over 1000, and bolted to the floor if you can, with many large diameter locking bolts and double walled heavy gauge steel) Only use little ones for extra fire protection.
Some of the sentry safes are for water also. I'd look for those instead of only fire.
