Find a local cue dealer who can write you a receipt for the value of the cue, and if possible inflate their worth. The insurance company will only give you the depreciation amount, not the actual cash value until you have replaced the items and show them the purchase price.
I have had my cues stolen twice out of my truck, and one of the times I watched it happen out of my office window. (Guess I will never learn) But the most important part is do not tell the insurance company that you play tournaments, or gamble or make any profit from playing pool. They will insist that you should have picked up a business policy and they will not cover the cues as they see it as a business asset. I had them tell me this when my cues were stolen last June, I had been fighting with them for 9 months and finally get paid in April.
Good luck to you, there is nothing worse in this world then a thief.
