I can only guess, but they can be found around 40-70r each in a public market. Not easy to get that many unless you have built a special nether structure and put a good amount of time farming it. You might find them cheap, but not in such a large amount. So, if I was auctioning, I would expect to get a min of: 40 * 64 * 27 = 69120 If I was trying to buy that many at once, I would be a fool to expect to get them that cheap and wouldn't be surprised to see it go so high as: 70 * 64 *27 = 120960 Prices are always based on what a buyer and seller are willing to agree upon, so I can't really say some exact price. I'm not making an offer to buy or sell, but a range based on my experience in the market place.
