Well here's the thing. You are asking someone to provide you with a free pool cue valuation service. Typically professional cue valuation services that are any good, cost some money. You are also asking every-day pool players to provide you with valuation advice on pool cues - something they probably only buy one or two of, every 5 years or so.
Furthermore, the valuation of the cue (or any item for sale) is a function of the supply in the marketplace of that particular cue, and a function of the demand for that cue at any given time. Since it is virtually impossible to know these two values unless you are a cue sales specialist (which 99% of all billiard players are not) it means you'll have to come up with your own price (what it's worth to you) OR put it up for auction.
At auction, if your asking price is too low, more bids will be enticed. The more bids you get, the higher the price becomes. The market determines the price for you.
As for your judgment about the quality of the forum, it really means nothing. Since you have not contributed anything to the forum before you came here asking for something, I don't consider your opinion to be valuable or valid. You are frustrated because you didn't get an immediate response on a question that less than 1% of all billiard players are qualified to answer.
Based on the fact that your cue has no history (that you know of, or that you can prove) it is probably worth no more than a commodity cue. This means that to the average player, it's worth no more and no less that "standard" low-priced common pool cue that can be found brand new for a low cost.
Brand new Helmstetter cues are going for $200 to $400 dollars. That's brand new.
