The item in question refers to a United States dollar coin minted in 1979 composed of a copper-nickel clad alloy. These coins were produced by the U.S. Mint and circulated as legal tender. Examples of the coin feature an image of Susan B. Anthony.
These coins, while no longer in production, represent a period of transition in American coinage. They are collected by numismatists, and their historical significance lies in their connection to the women’s rights movement. The coin briefly replaced paper dollars due to perceived economic advantages, though its unusual size led to public resistance and a short circulation period.
