There are a few known double struck Mercury Dimes that were struck at the Philadelphia Mint. This one is exceptional due to it showing 2 full dates, the S-Mint mark from San Francisco, and is also a rarer date!

A regular 1926-S Mercury Dime in AU 55 is worth $500, and in MS 65 is worth a minimum of $2,500. A 1945 Mercury Dime (common date) is worth $10 in AU 55 and $50 in MS 65.

This unique San Francisco minted double struck Mercury Dime is fresh to the market and is an exciting and rare major mint error.

Here is another extremely rare San Francisco Mint double strike with the second strike off-center on an Walking Liberty Half Dollar. Click here for more info.
