These are the famous - and short lived - "Educational Series" of silver certificates. Produced in 1896, they are considered by many to be some of the most beautiful bills ever produced by the US government. Each has an allegorical scene on its obverse: The $1 bill is "History Instructing Youth", the $2 is "Science presenting steam and electricity to Commerce and Manufacture", and the $5 "Electricity as the Dominant Force in the World". The $1 also contains the names of prominent Americans like Lincoln, Irving, Adams and Faragut. They each have the faces of prominent Americans on their reverse: George and Marth Washington on t $1, Robert Fulton and Samuel Morse on the $2, and Ulysses Grant and Philip Sheridan on the $5. The bills were designed by muralists, and were extremely detailed. They were controversial, but less for their detail and more because of the naked breast visible on the $5. Designs were being prepared for a $50 bill, but the idea was canned for more utilitarian designs in 1899.
