I sold a Ram's Hammer in presearing for 25g. It took some time, but eventually someone came. Apparently he was there by accident and wanted to quest with me. I pressured him into buying it and then quested with him
Anywho, I suggest going from district to discrict, perhaps even prepare a little sale speech (I used notepad for mine and pasted the lines I had prepared into GW's trade channel) or go for the simple approach:
Ram's Hammer | 7-11 DMG | +10% DMG | 25G @ Training Ground Ascalon City
