It's not April 1st. Probably forgeries? From Bloomberg:
"June 12 (Bloomberg) -- Italy’s financial police said they asked the U.S. Securities and Exchange Commission to authenticate U.S. government bonds found in the false bottom of a suitcase carried by two Japanese travelers attempting to cross into Switzerland.
The bonds, with a face value of more than $134 billion, are probably forgeries, Colonel Rodolfo Mecarelli of the Guardia di Finanza in Como, Italy, said today. If the notes are genuine, the pair would be the U.S. government’s fourth-biggest creditor, ahead of the U.K. with $128 billion of U.S. debt and just behind Russia, which is owed $138 billion."
Go big or stay home.
