Deon, this is just my opinion, based on my own experiences. Your knife was a 'private' limited edition by Schrade, commisioned so to speak by the NAHC. Schrade did these 'privates' for a lot of different clients, and those clients sold or gave away the knives as they wished.
Some 'Privates' seem to do better than others. I'd pay a bit more for one marked LL Bean, Adolphus Busch, or 'Village of Ellenville', but that is just me. Ducks Unlimited members pay much more for Schrades celebrating that organization than I would. And I have no interest at all in a Schrade marketed by the Universary of Alabama.
To a dedicated member of the NAHC, trying to assemble a complete collection, yeah, he would pay a more. The average Schrade collector?? Well, what do you other guys think?
Good listing of many (be impossible to know just all of them) of the Schrade limited editons, commemoratives, private limited editions, in Bernard Levines Guide to Knives and their Values, forth edition.
