I have an "all risks" insurance policy, except for the exclusion of loss from an unlocked car, through Historic Firearms . I'm at home and my policy is at the office but if I remember correctly their minimum coverage is $35,000 and the premium for that is $125 per year which is .36% of insured value per year - I call that cheap. Also, it does not require scheduling individual items except for those guns individually valued at $10,000 or more.

At only $125 a year not insuring is foolhardy.
