Last time one went up at auction, sold for around 150k, but it was bundled with a couple other promo items. Search the auction forum if you want to see the specifics! As for the number of them, no idea. I could not make it to the event, so missed out on the fun. I have heard that stacks were dropped, however who knows how may were redeemed, or 'drunk' since then. (Yes, rumor has it that if you drink your eggnog, you get a bucket out of it!)
