Ok ur both useless.. end of.
On Olympus server i would say around 70m-100m maybe. This is the general price for all +7's 85 on Olympus, as for Greece it could be different, but use that as a general guideline i think.
Also you can check the stall network for spears and see if there are any there, and compare prices with them. This is how i base alot of my prices.
