I have my knives and firearms under a seperate policy. It hardly adds anything to my monthly homeowners payment, and the peace of mind it gives is worth it. My agent has an ongoing list with values, descriptions, serial numbers, etc, which I update monthly, as the collection is constantly changing. I am going to invest in a quality (heavy!) safe within the next six months (I'm waiting until we move into our new house so I don't have to move it twice!), but I will continue to keep the policy. Updating it can be a pain, expecially after an active month of buying and trading, however it's also kind of fun. I should mention that my agent is a pretty cool cat, who understands afflictions like knife collecting, firearms, etc. This probably helps a great deal.
