What is the value of my Condor 81 SSG Knife?

I was just wondering if this knife was of any value, as I found it in my basement, in a bunch of old boxes. The blade is marked, CONDOR U.S.A, with the model number 81 SSG and Pat. Pending. On the other side, Seizo Imai, Seki Japan with model number A1- 07042. And to note, there is an etch of a condor on the bolster.

See if a similar knife is on sale on e-bay./
