Everybody is looking for a deal. Buyers and sellers.
If you are asking for general knowledge purposes, it is gonna be one of those things that you'll never get a definite answer to.
If you want to sell it and want to maximize the sale price, you can hope to find someone who has to have it, has money and doesn't try to whittle you down (and doesn't straight up commit a crime to get it).
Or, you can put it on flea bay. That is the biggest marketplace and you will absolutely get fair market value for it. If you have never sold on eBay though, you might want to give an experienced seller a %of the sale price to list it for you. Buyers treat new sellers with caution and will generally not bid as high for a given item as they might from an established seller.
Finally, strong likelihood someone will see this thread and reach out to you about it.
That cue is not going to fund your retirement or college or buy you a house, sorry to say...
Unique looking cue, for sure. Best of luck
