Based on the provided information and established numismatic knowledge, the value of a 1979 Susan B. Anthony dollar depends almost entirely on its specific characteristics, such as its mint mark, condition, and whether it is a rare error variety. The provided context from Greysheet.com indicates that values for these coins are tracked and vary by issue, but the specific data is not present. The second source is irrelevant to the query. For the majority of these coins found in circulation, the value is simply their face value of one dollar.
The 1979 Susan B. Anthony dollar was produced at three different mints: Philadelphia (P), Denver (D), and San Francisco (S). Coins from the Philadelphia and Denver mints are exceedingly common, and unless they are in pristine, uncirculated condition, they are only worth one dollar. Even in a brilliant uncirculated state, their value typically only increases to a few dollars due to the large number of coins that were saved by collectors at the time of their release.
A significant factor that can elevate the coin's value is its condition, or grade. Numismatists grade coins on a scale, and a 1979 dollar that is certified in a very high Mint State grade can be worth more to a collector. For example, a professionally graded specimen in a top grade like MS-67 might command a price of $30 to $50, but finding a coin in such a high state of preservation is exceptionally rare.
The most notable factor that determines if a 1979 dollar is worth a significant premium is the presence of a die variety. Specifically, the 1979-P "Wide Rim" or "Near Date" variety is a sought-after error. This version, which resulted from the use of a modified proof die for striking circulation coins, features a thicker rim that comes much closer to the "1979" date. A standard 1979-P coin has a noticeably thinner rim and more space between the rim and the date. This "Wide Rim" variety is scarce and can be valued from $20 in circulated condition to over $100 in high uncirculated grades. Therefore, while most 1979 Susan B. Anthony dollars are worth only their face value, careful examination for this specific variety is warranted.
