A spectacular circulating coin - that no longer really circulates - the USA John F Kennedy Half Dollar first came into being in 1964, following the assassination of the then President. Measuring 30.6mm in diameter, it is a large circulating coin, and features JFK on one side, and the iconic USA Eagle seal on the other. These are surprisingly spectacular coins, and among my personal favourite in the world.
Available here in official US Mint rolls of 20 mint-marked coins each, the 2020 JFK Half Dollar was struck at either the Denver or Philadelphia mints. Depending on your fancy you can order either a Denver Mint roll, a Philadelphia Mint roll, or save $10 and order a roll of each!
