Ron Guth: By 1856, the vast majority of the lower-weight silver coins had been removed from circulation and the arrowheads that had been placed on either side of the date from 1853 to 1855 were deemed no longer necessary. In 1856, the Philadelphia Mint produced nearly 5 million Half Dimes, a hefty mintage for the 1850s but certainly not the largest. The result are numerous survivors covering a full range of grades from Good to MS66. The finest example is a single PCGS MS66+.
Fully struck examples are surprisingly scarce. Many examples show weakness on the denticles. On some examples, the denticles are so flat as to be almost non-existent.
