Grand Watermelon

 
  The $1000 “Grand Watermelon” note pictured above is, as of this date, the most expensive US banknote ever sold. A world’s record price of $2,255,000 was paid for this note, more than double the previous record. Heritage Auction Galleries of Dallas, Texas (www.HA.com) brokered the private transaction between two collectors.
  The only other known red seal Grand Watermelon is in the museum at the Federal Reserve Bank of San Francisco.
