Not as much as you think or hope. ebay is the best place to get an idea of what they are going for. When you sell a used bow if it has 0 shots or a million it goes without a warranty, unless it is an Elite.
Would guess it will sell in the range of $200-$275. That is what the shop owner will sell it for. He will give you less as he needs to make a profit by reselling. You would be better off selling it on ebay, Craigs List, or the classifieds here or Archery Talk.
You walk out the door with a bow the value goes down 20%. At a year you will get about 50% or purchase price. They don't hold value.
