Early reports seem to indicate there were only a few winners, though. The exact number remains unknown, but between three and five winners have bought Bitcoin through this auction. Interestingly enough, the winners purchased 13,999, 6,517, and 1,999.99 BTC respectively. Quick calculations tell us 1,999 Bitcoin is missing from the 24,518 BTC total. That particular lot remains unclaimed [at the time of writing].

That is quite a large amount of bitcoins. Was a bid made for this lot and the winner hasn't come forward to claim them?
I don't think there was a minimum bid amount specified for the bitcoins.
