how much are dragon swords worth?

hello all and i am new to this selling stuff.

how much is a blue dragon sword worth?

it has 13 - 19 damage and i think a couple bonuses
a party member wanted it really bad

is it worth a lot?

Not very much. A max damage one can go for 2-3k.

People have finally got it in their head that a dragon sword isn't good. You can't upgrade it at all. A 13-19 one isn't very good. If you can sell it for 1+k you are lucky, and should do so.
When I get them like that I salvage for the Firey Hilt.
