By the simple fact that you referred to this event as "The Bob Hope" I am compelled to comment and share my two cents.
I grew up in the Bob Hope Chrysler Classic era myself. When this, and the Crosby or AT&T in Monterey were the two flagship Pro-Am events. Ironically enough, it was this very season that I realized, the LPGA hosts a Pro-Am of their own, and it draws the names the PGA used to. I can't help but think it's due to the fact that, even though the pros tear up the desert courses, the ams have always struggled. Not to mention the players on the LPGA Tour are no longer the stereotypical "dikes on spikes." But rather, not only being pretty damn cute, have a game that is fun to watch.
I think the best thing that could have happened to this tour stop in the desert was picking up a sponsor as major as American Express. I say, because the big name Ams have clearly chosen the LPGA event, the PGA should drop the pro am portion and make it a full fledge tour stop held on the Stadium Course. Then leave the big draw pro am to Pebble Beach.
Once upon a time I had a goal to purchase every set of irons the Hogan Company made. With the added guideline that each set I purchased had, not only matching serial numbers (such as the number you found on the ferrules), but also had original grips.
I have a few set of Power Thrusts, I didn't pay more than $175 for each.
As mentioned, eBay is a great tool for finding a resale value for whatever someone collects. If you have an eBay account, log in. In the search bar type in the set you want to sell. From there you will find another tremendously helpful tool. Click the box to search "Completed Listings". You'll be able to scroll through other eBay users whom have sold similar sets and what they sold their sets for.
While I have been out of the hunt for a number of years, I still have most of the better sets I purchased. And as a collector, I cant see a set other than one totally untouched, going for more than $200...
