I had a serious equipment burglary incident once, and my homeowner's insurance was wonderful. Fortunately, I still had receipts for all of it. But because I also recorded serial numbers, those went to the police report, and that allowed a search warrant of the suspects once an item being sold matched one of those numbers; and that, along with fingerprints, led to an arrest and conviction, and the recovery of all my items with the exception of one lens, which the insurance company assigned full replacement value. But there were prepared to replace the full 18K in value if necessary. And when my brother accidentally dropped a few items, including a camera I loaned him, his homeowner's policy gave him full replacement value. But neither of us ever abused our insurance for frivolous reasons. That DOES make a difference.
During my day job providing equipment to contractors, 30% of our tool business was theft replacement. Every week multiple insurance estimates were done, often in the tens of thousands of dollars apiece - I'd say 20K was about the average. Many of these were in fact full replacement policies. Of course, the contractors paid quite a bit for such policies in this high risk theft area; but that level of coverage was absolutely necessary.
