While the provided context from the search results does not contain the specific measurements, the answer to the size of a silver dollar is a fascinating piece of numismatic history. When you picture a classic U.S. silver dollar, like the iconic or Peace dollars, you're thinking of a coin with a very specific and substantial feel, and for good reason.
The standard and most widely recognized size for these historic silver dollars is a diameter of 1.5 inches (or 38.1 millimeters). This consistent measurement is what gives them that satisfying heft and presence in your hand. For over half a century, from the Morgan Dollar's first minting in 1878 to the end of the Peace Dollar series, this 1.5-inch diameter was the trusted standard for America's largest circulating silver coin.
It's worth noting that the modern American Silver Eagle, a bullion coin first released in 1986, is slightly larger. It measures about 1.6 inches in diameter (or 40.6 millimeters). However, if you're asking about the classic coin that jingled in the pockets of people in the Old West and through the Roaring Twenties, the definitive answer you're looking for is 1.5 inches across.
