Ron Guth:
The 1796 Half Dime is the first year of the Draped Bust design type. It is a scarce date that it is at least as rare, if not more rare, than the 1794. Very few Mint State examples are known, the most notable of which is a single MS67 example that was first certified by PCGS in late 1989. The unusual "LIKERTY" variety was not a spelling error -- the "K" is actually a broken "B." The only other variety of this year is an overdate: 1796 over 5.
Varieties (2):
Valentine 1 - "LIKERTY" - Scarce
Valentine 2 - 1796/5 - Very Rare
