So, I tried using the AH and almost every comparable piece I saw was insanely priced (i.e., hundreds of millions). I have a hard time believing that most of those are selling, so what would you pay (gold or US dollars are fine)?
Hard to say, definitely tens of millions...with super items like this I usually start the auction on the AH at 10mil and let things take their course. Alternatively you could offer it here (safer) or official forums (beware scammers) for bid and see where it goes, avoid that 15% tax
