Just a few weeks after Silk Road 2.0 and its owner got seized, the US government posted this:

THIS SEALED BID AUCTION IS FOR A PORTION OF THE BITCOINS CONTAINED IN WALLET FILES THAT RESIDED ON CERTAIN COMPUTER HARDWARE BELONGING TO ROSS WILLIAM ULBRICHT, THAT WERE SEIZED ON OR ABOUT OCTOBER 24, 2013 (“COMPUTER HARDWARE BITCOINS”).

Apparently it’s from the first Silk Road. Pretty comical.
