A historic United States silver dollar, such as the Morgan or Peace dollar, is substantially larger and thicker than a standard U.S. quarter. The size difference is immediately noticeable when the two coins are placed side-by-side.
Based on coin specifications, a classic silver dollar has a diameter of 38.1 millimeters and a thickness of 2.4 millimeters. A U.S. quarter, by comparison, has a diameter of approximately 24.3 millimeters and a thickness of 1.75 millimeters. This means the silver dollar is nearly 14 millimeters wider and significantly thicker, giving it a much more substantial feel and appearance.
It is important to distinguish these traditional silver dollars from modern, non-silver dollar coins currently in circulation, such as the Presidential or Native American dollars. These contemporary dollar coins are much closer in size to a quarter, with a diameter of about 26.5 millimeters. The American Silver Eagle, a modern silver bullion coin, is even larger than the historic silver dollar, measuring 40.6 millimeters in diameter.
