The US minted the 1870 half dime with no mint mark and also the 1870 S half dime. The mint mark, when present, can be found on the reverse side of the coin above the bow.

There is only one 1870 S half dime known to exist. In 1870 a new mint facility in San Francisco was being built and there was a plan to strike a complete set of coins with the San Francisco mint mark. However, not every single coin denomination was minted in San Francisco that year. Mint officials struck at least one 1870 S half dime for display at the mint. This coin ended up in the hands of a private collector.
