The Susan B. Anthony Dollar is a coin that was first minted in 1979 to honor the women's rights activist Susan B. Anthony. It features her portrait on the front and an image of an eagle on the back. The coin was intended to promote the use of dollar coins in everyday transactions. Despite its significance, the Susan B. Anthony Dollar faced challenges in circulation due to its similarity in size and color to the quarter. Production of the coin continued until 1981, and it was later minted again in 1999 as a commemorative piece.
