Based on the provided information and general numismatic knowledge, a 1921 silver dollar with no mint mark was minted in Philadelphia. The Philadelphia Mint did not use a mint mark on Morgan dollars, so its absence is standard for these coins.
The value of a 1921 Philadelphia Morgan dollar is highly dependent on its physical condition, also known as its grade. The 1921 Morgan dollars are quite common, as over 44 million were produced at the Philadelphia mint.
For a coin in circulated condition, meaning it shows signs of wear from being used as currency, its value is often closely tied to the spot price of silver. These coins typically trade for a small premium over their silver melt value. As of late 2023, this would generally place their value in the range of $25 to $40.
If the coin is in uncirculated or "Mint State" condition, its value increases significantly. Collectors pay a higher premium for well-preserved examples with strong original luster and minimal scratches or marks. A professionally graded, high-quality uncirculated 1921 Morgan dollar can be worth anywhere from $50 to several hundred dollars, with exceptionally rare, top-grade examples fetching even more.
