I'd be very surprised if the highest priced one sold above $800. I don't think the market will move to the sale price either because of the sale.
Each auctioned block was 3k bitcoins. That's a lot of money, but it's what Bitpay sells in about a week if we are to believe their numbers. I would expect them to be happy to sell to you at a percent or two over spot. I mean, it would be practically free money for them. So I find it completely unreasonable that someone would pay even $800.
Not that I think it matters very much. We already have an inkling about what players are active in the Bitcoin space and what the volumes involved are, at least to an order of magnitude. The only reasonable argument for a post-auction rally would be that any one of the losing players ended up at an exchange instead, seeing as they had already done the due diligence on the deal.
