RE: how much?
Buyer bewarewhen it comes toused bows, especially one that old. Also, the fact that it's a High Country means that it certainly isn't a very popular bow and would be very difficult to resale to anyone else, ever. Honestly, there's no way the bow could be worth anymore than$150. Also, you might want to compare it's value to a similar bows on Ebay, this will generally give you a good indication of what something it going for.
Good luck and welcome to the forums
