The first one-dollar bills small size notes were issued as silver certificates under Series of 1928. The Treasury seal and serial numbers were dark blue. These are commonly known as " Funnybacks" due to the rather odd-looking "ONE" on the reverse. These were the first notes to be called funnybacks. The reason they are called funnybacks is because of the unique design on the back of the bill. Blue seal
