What is a 2003 Series A one dollar bill?

A 2003 Series A one dollar bill is a U.S. banknote that was issued as part of the Federal Reserve Note series, featuring George Washington on the front and the Great Seal of the United States on the back. The "Series A" designation indicates it was the first redesign of the one dollar bill after the 1996 series. While it retains the traditional green color and design, the 2003 Series A bill incorporates some updated security features. Collectors often seek it, especially if it has unique serial numbers or is in uncirculated condition.
