How much would you pay for a sword?

I bought a 300 dollar eragon sword becuase i thought it would be really cool. Now i don't want it becuase its too big. Would somebody even buy it, it is a collectors edition. I dont how much to sell it for, so what would be a good price?
Update: I know, it was a dumb thing, but i just want to know how to get rid of it. please help!
