I recently called State Farm about insuring my collection. The woman I spoke to basically told me to estimate each individual item that was valued under $5,000, complete with pictures of the items and the resources I used to determine the estimate. For individual items valued over $5000 each, they said that they would have to send an individual appraiser out.

In case things were stolen or damaged, she said at that point and time they would send someone out to reassess the value of each item, basically throwing out my original appraisal.

I have homeowners and car insurance through State Farm. If memory serves me correctly, the cost to insure my collection was going to cost approximately 0.8% of the total valuation of my collection annually. Hope that helps.
