The front features the portrait of Civil War-era General George Gordon Meade who commanded Union Army troops at the Battle of Gettysburg.
The three ornate zeros in the back look like watermelons, thus given the note it's nickname "Grand Watermelon".
This note, graded PCGS Extremely Fine 40, was sold in January 2014 by Heritage Auctions in Orlando, Florida for $3,290,000, a world record price
paid for a United States bank note.
Interestingly, the same note was previously graded PMG Very Fine 35 and sold by Heritage Auctions in 2006 for the then record price of $2,255,000.
The only other known Grand Watermelon note is in the Federal Reserve Bank of San Francisco Museum.
