The US Marshals neglect to mention the auction rules, for their June 27 auction of bitcoins seized from Silk Road. I surmise that it is a first price sealed bid auction, but it's a little interesting that is regarded so clearly as the default that nothing needs to be said...
They were earlier in the news for cc'ing rather than bcc'ing all the registered bidders in what was supposed to be an anonymous auction:
US Marshal CCs, rather than BCCs, those interested in anonymous Bitcoin auction
A simple CC/BCC mistake embarrasses agency in charge of selling off Silk Road funds.
