Hello! That's a great question about a very interesting coin. It's a common point of confusion, so I'm happy to help clarify its value for you.
First, it's important to know that the 1979 dollar coin, known as the Susan B. Anthony dollar, is not actually made of silver. Although people often call them "silver dollars" out of habit, these coins are composed of a copper-nickel mixture. This means their value isn't based on precious metal content. The "S" mint mark on your coin indicates it was struck at the San Francisco Mint.
The value of a 1979-S Susan B. Anthony dollar depends heavily on its condition and whether it was made for circulation or as a special proof coin for collectors. A standard 1979-S coin that has been in circulation is generally worth only its face value of one dollar. If you have one in brilliant, uncirculated condition, it might be worth a little more, typically around $3 to $5.
San Francisco also produced proof versions of this coin for collector sets, which have a much shinier, mirror-like finish. These are also quite common and are generally valued in the range of $5 to $10. For a precise value, the specific condition of your coin would need to be assessed by a professional.
