Based on general numismatic knowledge, a 1979 Susan B. Anthony dollar's value is typically modest, though certain factors can increase it. It is important to first clarify a common misconception: despite being referred to as a "silver dollar," the 1979 Susan B. Anthony dollar intended for circulation is not made of silver. It is a copper-nickel clad coin, composed of a pure copper core with an outer layer of 75% copper and 25% nickel.
For the vast majority of these coins that are in circulated condition, they are worth only their face value of one dollar. The U.S. Mint produced hundreds of millions of them in 1979 across the Philadelphia (P), Denver (D), and San Francisco (S) mints, making them very common.
However, the value can increase if the coin is in uncirculated, pristine condition. A standard 1979 business strike coin that has never been in circulation might fetch a small premium, typically between $2 and $5. The value is highly dependent on the certified grade.
The most notable exception is the 1979-P "Wide Rim" or "Near Date" variety. On this error coin, the rim is thicker, and the date is closer to the edge than on the standard version. This specific variety is much rarer and is sought after by collectors, with values ranging from about $10 in circulated condition to over $50 for high-grade uncirculated examples. To determine if you have this variety, you would need to compare it closely with a standard "Narrow Rim" 1979-P dollar.
