Circa 1985 my State Farm homeowner's policy included $1000 of gun coverage with an added rider for $2500, for a small fee. The big shock came when I wanted more coverage! Anything over $2500 was at straight risk and 5% of inflation adjusted each! That's $50 a year for every $1000. My collection of guns at one point was $17,000 ($850 a year) and increased every year by the percentage of inflation! + the value of any additional guns. Then they got pushy about storage and security. At the time $850 bought a very nice gun safe, but buying one didn't lower the cost of coverage! It was ridiculous!
The NRA sells some and advertises for better priced companies.
