1963B $1 'Barr Note' Federal Reserve Note Grades xf+. Among the most sought-after U.S. paper money of the late 1960's are the short-lived "Barr" Notes. These distinctive $1 Federal Reserve Notes bear the signature of Joseph W. Barr, who served as Secretary of the Treasury during the last 28 days of President Lyndon B. Johnson's administration. Barr was replaced when President Nixon chose a successor. Due to Barr's short term, his signature appeared only on the $1 notes of Series 1963B.
