Yes, its worth more. I see them on feebay go upwards of $500 sometimes, for even a small one with papers. I have a mint BG-42 large regular sebbie ( no papers or box ), my first crk folder and I got it for $280 on ebay. So you do see them cheaper sometimes, but when I got mine several years ago, the regulars were more available. I also got a small P style sebbie on there for $220 with ATS-34 blade. So there are deals to be had if you look and jump on a deal the second you see it.

So yes, its definately worth more, like xm's, it depends on the week it seems or someones lack of knowledge or value. If you have one, I would say keep it because the value will definately hold and will rise over time. Just look at the OPR, you see their prices double as of late.
