The diameter of dollar coins issued by the United States Mint varies depending on the specific series:
- The Susan B. Anthony dollar , minted from 1979-1981 and again in 1999, has a diameter of 26.5 mm (1.043 in).
- The Sacagawea dollar , minted from 2000 to the present, also has a diameter of 26.5 mm.
- The Presidential dollar series, which honored each deceased president from 2007 to 2016, and again in 2020 for collectors, shares the same diameter of 26.49 mm (1.043 in).
- The Eisenhower dollar , minted from 1971 to 1978, was larger at 38.1 mm (1.5 in).
It is worth noting that the Sacagawea and Presidential dollars are often referred to as “golden dollars” due to their manganese brass composition, which gives them a golden color . The Eisenhower dollar was also minted in a larger size, making it the only circulating “large dollar” to be minted in cupronickel.
