There is no price guide for the UK. I don't know of any for dealer chips, either. As for the value, well, you have heard it a bunch of times on the board. With the current condition of the hobby, it's anybody's guess, except for very common or very established chips. The more offbeat, the more the value is what you or a potential buyer will pay for it. I think you are solidly in that category with this chip.
