I've seen several brand new ones listed on e-bay recently for $200, and they didn't sell. They had a big price jump from around $50-$75 to over $200 when word got around that there would be no more printed. After that little flurry, the value has dropped back down slightly. I'd say yours should bring $150 or so. If you have the other book (shots moves and strategies), they are worth considerably more as a set.
