First ever US Silver Dollar in Braille. This 2009 Silver Dollar honors the 200th anniversary of the birth of Louis Braille, the man who developed the system to help the visually impaired to read and write. This profound invention has increased the quality of life for millions and granted them independence. Only 400,000 are to be minted, a very small number for a one year only issue Silver Dollar from the U.S. Mint. Graded by NGC Proof 69. The Letters BRL in Braille are on the coin.
