Hello! That's a great question about a very interesting coin.
While the provided sources are good places to look for coin values, they didn't include the specific pricing information for the 1979 Susan B. Anthony dollar. Based on general numismatic knowledge, I can certainly help you out.
First, a common point of confusion is the "silver" in the name. Despite often being called a silver dollar, the 1979 Susan B. Anthony dollar is not made of silver. It's a copper-nickel clad coin, so its value isn't based on precious metal content.
For the vast majority of 1979 Susan B. Anthony dollars that you might find in your pocket change, they are worth their face value of one dollar. Millions were minted, so they are not rare in circulated condition.
However, a few factors can make one worth more. The value increases significantly if the coin is in uncirculated, pristine condition, often fetching a few dollars. The mint mark, which indicates where the coin was made (a small P for Philadelphia, D for Denver, or S for San Francisco), also plays a role.
The most important thing to look for is a specific error variety from the Philadelphia mint known as the "Wide Rim" or "Near Date." On this version, the date "1979" is much closer to the coin's rim than on the common "Narrow Rim" version. If you have a 1979-P Wide Rim variety, it could be worth anywhere from $20 to over $100, depending on its specific grade and condition. So, it's definitely worth checking the rim and date on any 1979-P dollars you have
