The size of a United States silver dollar varies depending on the specific coin series in question. The dimensions for the traditional silver dollars intended for circulation differ from the modern bullion coins produced for investors and collectors.
Historically, prominent silver dollars such as the Dollar (minted 1878-1921) and the Peace Dollar (minted 1921-1935) share the same dimensions. These coins have a diameter of 38.1 mm and a thickness of 2.40 mm. The later Eisenhower Dollar, which was also produced in a silver version for collectors from 1971 to 1978, has the same 38.1 mm diameter but is slightly thicker at 2.58 mm.
In contrast, the modern American Silver Eagle bullion coin, which has been produced since 1986, is larger. This contemporary silver dollar has a diameter of 40.6 mm and a thickness of 2.98 mm, making it noticeably bigger than its historical circulation counterparts.
