1980 Kennedy Half Dollar

A small but notable change took place for the half dollar in 1980. For the first time, the “P” mint mark was included for coins struck at the Philadelphia Mint. Since the introduction of the denomination, all coins struck at Philadelphia did not include a mint mark, while coins struck at other facilities included the mark, with only a few exceptions. The “P” mint mark was now included in the same location as other mint marks, on the obverse between the date and truncation of the neck.

The 1980 Kennedy Half Dollar (Buy on eBay) had somewhat higher mintages in circulation strike and proof formats. Mint state examples of the coins always remain readily available within government issued mint sets and proof sets, which are affordably priced for this year.
