I can generally get 3.5-5 mill for a rare colored Cu fully trained on GL. That is with decent stats and resists. Last week I sold what I consider a poor Cu stat/resist wise for 4 mill, soley because it was white. I'm sitting on a very nice red cu right now (okay hp/strength, very nice resists) with an asking price of 5 mill. If it doesn't sell, that's cool, I'll hang onto it myself, as I'm not in dire need of the gold or the stall space. Normal or non-rare Cu's fetch 2+ mill for me, fully trained, depending on stats/resist.
