In 1817, the U.S. Mint produced over 1.2 million Half Dollars. Among those, researchers have identified thirteen different die varieties, including two overdates (1817/3 and the exceedingly rare 1817/4) and one with a so-called "Punctuated Date" (actually a die chip between the 1 and the 7). This date is plentiful in most grades, though Mint State examples are scarce to rare, a fact exascerbated by the popularity of the series and the wide distribution of known examples. At the top end, the best examples rate MS66. All of the coins in the PCGS CoinFacts Condition Census are MS65 or better.
