1901 Dime Value: No Mint Mark, S (Updated 2026)

The 1901 dime value calculator is quite helpful for understanding potential coin worth. It breaks down the differences between the three mints clearly, noting that the San Francisco issue is a semi-key with a lower mintage. The detailed description of the FS-501 variety adds good depth for serious collectors. I appreciate that the tool allows you to select specific errors like clipped planchets or off-center strikes. This level of detail helps in identifying rare specimens. The reference to PCGS and Heritage data provides a trustworthy basis for the estimates. One question remains: does the AI photo estimate match the manual input results exactly? It would be great if the tool showed the data source for each price tier to increase transparency for users.

The self-checker makes identifying the rare S mint mark so much easier for beginners like me.

The website presents a well-structured approach to 1901 dime valuation, clearly distinguishing between the Philadelphia, New Orleans, and San Francisco mints. The inclusion of specific mintage figures, such as the 593,022 coins struck in San Francisco, adds credibility to the semi-key designation. The error varieties are explained with sufficient technical detail, particularly the FS-501 O/Horizontal O variety. However, the transition between the self-checker and the full calculator feels slightly disjointed. While the AI-powered photo estimate is a convenient feature, it remains unclear how precise these instant estimates are compared to the PCGS and Heritage data cited. The content is informative, but the separation of the verification tool from the price calculator might confuse users seeking a single comprehensive answer. Overall, it is a useful resource for collectors, though the interface could be more integrated for a smoother user experience when evaluating coin value and condition simultaneously.

The website provides a comprehensive breakdown of 1901 Barber dimes, covering all three mints. I found the mintage data particularly helpful, especially noting that only 593,022 coins were struck at San Francisco. The detailed error guide for the FS-501 variety is clear and accurate. It is reassuring to see that the values are based on PCGS and Heritage data, adding credibility to the price estimates. The self-checker tool effectively helps users distinguish between the common Philadelphia issue and the rare semi-key San Francisco variety.
