Wolf killer

I have a 2005 Bow Tech Tribute that still looks brand new. I bought it in the spring/summer of 2005 then changed jobs during the summer of 2005. I never hunted with it, I shot it less than 100 times. This bow has been sitting in its case ever since.
I want to trade it in on a new bow, what is a fair trade in value? I will be going back to the same shop I bought this bow to buy my new bow. Will this help my trade in value?

Thanks,

WK
