Value of a Pool Intairdril 1976 custom Rolex?

I have a Pool Intairdril 1976 custom Rolex that I am interested in selling, but I am unsure of what the appraised value of the watch is. Pool has been closed. I took the watch to a jeweler who told me the value of a 1976 Air-King Rolex, but he was not sure what affect the customization would have on the value. I checked a href="http://www.timeandgems.com/Watch-of-The-Week-Wednesday-5--Custom-Rolex_b_30.html" rel="nofollow"http://www.timeandgems.com/Watch-of-The-…/a for information. There was no price listed on the website, but it did say that the Pool Intairdril custom Rolex is a collector's piece. Any information would be appreciated.
