Try getting hold of Milo on here, I believe he collects older Abu Garcia reels.
Indeed I do, but my collector's focus is on vintage and collectible Abu Garcia Ambassadeur reels, especially those made in Sweden in the pre-1980 days.
The reel you are interested in selling is a big game salt water baitcaster, in the class of the more widely known Penn Senator 4/0.
While it is a nice reel to have and use, it is of little collectible value, as the market is swamped with them. A quick search on eBay will show you that many of them have been sold in the recent months, fetching little more than 20 bucks a piece on average, with NOS units in unopened boxes not fetching three figures.
My advice to you would be to clean it and service it (it's a very simple reel) and gift it to someone you know can put it to good use (e.g. someone who fishes for halibut and salmon in the chuck).
Cheers,
Milo
