I doubt it has any collector value. There is one listed on Craigslist for $100: http://boston.craigslist.org/bmw/spo/1615479329.html

Which I seriously doubt he will get. Several have sold on ebay in the $30 to $40 range. I bought one for $35 a few months back. The arrows are probably worth as much as the bow depending on what exactly you have. For your whole package, I'd be looking for $100 or so.
