Years ago I suggested that Az create a cue registry and charge a fee to have pool cues registered as owned by you.
As a practice, every ethical cue dealer, collector or just a periodic buyer should check that the cue seller is the owner.
I don’t expect every single cue to get listed but the more expensive, collectible, sentimental custom pool cues could.
Every single cue I own I’d register. Pawn shops should be required to double check which would be simple and easy.
There was little interest in creating this new cue registry which was disappointing to learn. I think it has potential and
wondered why. Some of my cues are valuable so I obtained a rider on my insurance policy for my guns and pool cues.
Having run a pawn shop in Texas, the biggest obstacle with theft recovery would be an accurate description on both the owner's end and then when it's pawned/purchased. This description should definitely include serial numbers or unique markings, wood types, veneer colors, types of inlays, etc but your average pawn employee likely knows very little about pool cues.
The cue owner should also have very detailed high-resolution pictures showing the full cue and any unique features of a cue. It should also include any supporting documentation like the purchase receipt or LoAs.
I can only speak to Texas, but there is a registry that all of the pawn/purchase data gets uploaded to for law enforcement and they search by pictures and/or description and the more information you have, the more likely they can find a match. Some do, but I don't believe pawn shops here are required to take pictures. That said, I've been out of that game for a while.
The high-resolution pictures and details would also be helpful for the insurance rider if that wasn't required to start with.
