1 Dollar (Louis Braille Bicentennial)

The Louis Braille Dollar: the first U.S. coin you can read with your fingers

Run your fingertip across the back of this coin and you feel three small clusters of raised dots. They spell BRL — Braille. It was the first time in U.S. history that a coin carried Braille you could actually read by touch, and that single design choice is the whole point of the Louis Braille Bicentennial silver dollar.
