Price check needed on r8 perfect spiked axe

I was wondering how much a perfect spiked axe rq8 would be worth
its 6 - 28 (rq8)
20/20 sundering
+ 30 health
(not inscr.)

Ty in advance people

edit: oops ye its 15^50 sorry :P

no damage mod?
salvage mods then merch it

if it should be 15^50
i'd say 15-25k or so
