Based on the information provided, it is important to first clarify that the 1979 dollar coin is not made of silver. It is the Susan B. Anthony dollar, which is composed of a copper-nickel clad. This is a common point of confusion, as the term "silver dollar" is often used colloquially for any dollar coin.
A 1979 dollar coin with no mint mark was produced at the Philadelphia Mint. During that year, the Philadelphia Mint did not place a "P" mint mark on the coins it produced, so the absence of a mark is standard for that particular issue.
The value of a 1979 Philadelphia Susan B. Anthony dollar in 2023 depends almost entirely on its condition. If the coin is circulated, meaning it shows signs of wear from being used as currency, it is typically worth only its face value of one dollar.
For a coin in uncirculated or mint state condition, the value increases. These coins can be worth a few dollars more than face value, generally in the range of $2 to $10. There is also a notable variety known as the "Narrow Rim" or "Far Date" 1979 Philadelphia dollar, which is scarcer and can be more valuable, potentially fetching between $5 and $35 depending on its grade. For professionally graded, high-quality examples, the value can be even higher.
