No need to pay for an " appraisal" the cue market for a cue like this is not even close to being set in stone. It is a cue that has a very limited market- why?
1. it would not appeal to 99.99% of current pool players under the age of 50.
2. it is out of reach financially for the vast bulk of the cue buying public.
3. the actual market for cue buyers of this type of cue is shrinking every day, as people 65 to 90 who , by far, are those who actually would know of this famous cue maker of the past , are mostly not buying more cues to add to their collections unless it is a fire sale on the cue.
4. the Reality is - if you want ACTUALLY to sell the cue- post in the for sale section of this site, follow the selling rules, vet your potential buyers as one needs to do on the internet, and start with an asking price of $4500. Be clear in your listing that you will strongly consider best offers.
5. Then just wait to see what offers come your way- refresh the listing often here by bumping it to the top if you do not get any early acceptable offers above a floor that you decide- should be somewhere between $3,000 and $4,000 in my opinion.
6. From about 25 years of doing this, and one who believes in actually selling cues and not just listing cues, my opinion is that ANYWHERE from $3K to $ 4K - I would take the money- but that is just me- others may differ.
