How much is an Epiphone Dot worth on trade in at a music store?

It is in excellent condition, no scratches and would include the case on trade.

Normally I would sell it outright, but I got gift certificates to my local store from everyone I know to the amount of like $250 total, and I am hoping to be able to swing a Gretsch Elliot Easton that is going for $399.

about 60% of its original sale price is an ok guideline.
