Mine is in a fire proof and moisture resistant safe that is installed in my floor. It is quite massive. The way I protect my coins is I have the profesisonally graded by a grading service that encapsulates them in thick air-tight plastic with a label describing what it is, date of minting, mint that produced it, condition grade and metals content. If you go to sell them to anyone who deals in coins you will get a better price for having this done and even if you never intend to sell than it will keep them safe for life.
