As a Floch reproduction, maybe $50 to $100. It`s 40 to 50 years old and has been passing as an original pre-45 EKI probably most of that time. In another 20 years or less, when most, if not all of us old timers are gone, it may become an "original" and be worth a considerable amount more.
Don`t feel bad about the cross not being original. I traded a valuable pre-45 Hitler print by Hoffmann for an "original" Nazi pocketknife once. The "sharp pointy thing" collector in me had never seen one like it and I HAD to have it. When I was told it was a " fantasy" piece made in the 1970s, I did not want to believe it and defended it`s originality. It took me a few months to accept it as what it was. In the end, I took it to a friend`s antique/junk shop and basically gave it to him because he thought it was so cool. He put it on display in a glass case. A couple of months later his shop burnt to the ground.
The knife is gone except for the pics I have of it and it still erks my azz that I traded that now rare Hitler print for it.
