I am trying to find the value of a knife I have. I won it in 1984 form the Pennsylvania Federation of Sportsman's Club. It is a Case XX. Its solid pewter commerating the 50th anniversary of the Pennsylvania Federation of Sportsman's Club, designed by Shaw-Leibowitz. 1000 were made and I have #0338. The blade is stamped with K1051 LSSP. Any info would be appreciated.
