Let's not forget that we won't receive any information at all concerning the auction:
6) What information about the auction process or results will the USMS release?
The USMS will contact the winning and losing bidders directly. The USMS will not release any information to the general public pertaining to the auction process or results.
i hope that there will be somebody trusted who placed a bid and lost, sharing what he has bidden. this way we know a minimum price per coin.
...how it affects the price... hard to say, i dont expect a big move yet... there is still the second auction. biders who lost will wait and bid again.
