Recommendation? Mad Dog 2002 Knifegnugen 3rd Place Winner

[Godstopper]

So I am having a hard time pricing this and I thought I would reach out. The For sale rules state I must be 100 percent sure on the for sale price so I figured I would start here.

Its a Mad Dog knife. With Knifignugen 2002 3rd hand engraved on the back.

Its a used knife but Its a famous competition.
