I think he's relatively new to the custom pool cue scene if I recall correctly, and his custom cues aren't really well known yet.
He's based out of Missouri, and seems to sign and date his cues.
I've been seeing the odd classified ad for Jeff Tucker cues on marketplaces like Facebook and eBay, etc, but not enough to get a feel for his pricing and the range of quality and complexity of his custom cues.
Everyone who has posted about them has good things to say. Here are a few comments:
Up for sale is my custom Jeff tucker. Guy makes phenomenal cues.
Want to show pictures of my new cue, which is a Jeff Tucker custom cue. The shaft is Kielwood, and is 30 inches long, and 11.75mm at the tip. Anyways, thanks for all of your help, and info about Jeffrey Tucker cues. This really does seem like a very well made cue, and it rolls dead straight (together and apart), which I was really happy to find out.
He makes great jump break cues. Not the best picture but he makes very pretty cues and great playing cues as well.
He made this 1 for me. He does awesome work. Jeff can do just about what ever you want.
In terms of value - unless you have a specific Jeff Tucker custom cue in mind, there's no point in discussing value. The price ranges wildly depending on the complexity of the cue, the materials used, the overall design aesthetics, and the cue's condition.
I can easily find 5-10 listings on Facebook Marketplace right now. Here are the price ranges of the first five I've come across:
