The 1796/5 Half Dime is an intriguing coin that raises some interesting questions. Usually, overdates occur on leftover dies from previous years, but they are usually of the same design type. So, was the placement of the 5 on this Draped Bust obverse simply a mistake or was it the intention, at some point, to strike a 1795-dated Draped Bust Half Dime? The 15 stars on the obverse may offer a clue because the the 15th state (Kentucky) was admitted to the Union in 1792, while the 16th state (Tennessee) was not admitted until 1796 (after a 1795-dated die with 15 stars would have been created).
The 1796/5 Half Dime is rarer than the 1796 "normal" date (LIKERTY) variety. At least ten different Uncirculated examples are known, the best being the Garrett-Pogue PCGS MS66.
