PC on hand axe 15^50

I am planning on getting a hand axe - max dmg with 15^50 dmg mod. With no other upgrades, how much are they worth, i am broke need to know how much gold I gotta farm... The req. does not matter, higher is better - cheaper.

req 13 - 10/15 k.

And req.12? Guess around 20... That is not much at all i can get it :]
