Based on numismatic information, the 1979 one-dollar coin you are referring to is the Susan B. Anthony dollar. Its value is highly dependent on its condition and the mint mark, which indicates where it was produced.
For most 1979 Susan B. Anthony dollars found in circulation, the value is typically just their face value of one dollar. These coins were minted in very large numbers at the Philadelphia (P), Denver (D), and San Francisco (S) mints. If the coin is in uncirculated, mint-state condition, its value might increase to a few dollars.
However, a specific variety of the 1979 coin from the Philadelphia mint (1979-P) is significantly more valuable. This is known as the "Wide Rim" or "Near Date" variety. On this version, the date is very close to the coin's rim, unlike the common version where there is a noticeable gap. A 1979-P Wide Rim dollar can be worth anywhere from $20 to over $100, with the price increasing substantially based on its certified grade.
In addition to the circulating coins, the San Francisco mint also produced proof versions (1979-S) for collectors. These coins have a brilliant, mirror-like finish and were not intended for circulation. A standard 1979-S proof coin is generally worth a few dollars. To determine the precise value of your coin, it is essential to identify its mint mark and assess its physical condition, as even minor wear can significantly impact its worth.
