Add in the cost of insurance to your expected appreciation
You can get insurance for your guns through Eastern Insurance.
They specialize in firearms, offer worldwide all risk protection. The minimum yearly premium is $125 and covers up to $35k in firearms. In addition no appraisals are needed on the guns unless a gun is valued over $10k. Because I live in a flood zone flood coverage is excluded from the policy.
