The weight of an Eisenhower dollar is contingent upon its specific metallic composition, as the U.S. Mint produced two different versions between 1971 and 1978. A distinction must be made between the coins intended for general circulation and those produced specifically for collectors.
The version that is properly termed an Eisenhower silver dollar was struck for the numismatic market and contains 40% silver. These coins, identifiable by their "S" mint mark, have a total weight of 24.59 grams. This composition consists of outer layers of 80% silver bonded to an inner core that brings the coin's total silver content to 40%.
For comparison, the more common Eisenhower dollars minted for general circulation are not silver but are instead made of a copper-nickel clad composition. These coins, which carry a "D" mint mark, a "P" mint mark, or no mint mark, have a total weight of 22.68 grams. Therefore, the silver-clad collector's version is slightly heavier than the standard circulating issue. This information is based on established numismatic specifications, as the provided context was insufficient to furnish these details.
