Gold wingblade 15^50

Need a little help....

I am looking for a gold wingblade req 9 or lower and 15^50 mod trying to figure out a fair price to offer. other mods i don't care about....any ideas?

OK so I take it noone can think of a reasonble base price that a gold 15^50 would fetch...I realise it all depends on req etc....but there has to be some sort of starting point!
I am seeing prices in lions from 30k- 100k for a gold wingblade...

req 9 would be 45k range... w/ no mods....
