In what years did they produce the Lincoln/Kennedy penny?
The Lincoln/Kennedy penny is a product of a manufacturing process applied to coins AFTER they have left the U.S. Mint. In other words, someone stamped Kennedy’s image onto a normal penny, making it a novelty item. This was NOT something done at the mint. So, since any penny could be stamped, any year could be on the penny. It doesn’t even have to be a penny — it is possible to have a Jefferson/Kennedy nickel or a Washington/Kennedy quarter — it just depends on what someone decides to stamp it on. There have been other things stamped onto Lincoln pennies — like a Liberty Bell, a U.S. map, and a pipe — but Lincoln/Kennedy pennies are probably more popular because of the “Astonishing Coincidences” between Presidents Lincoln & Kennedy. These are detailed HERE. I’ve sold these novelty coins for $1.00 each, or $2.50 each when attached to the Astonishing Coincidences card. Details and pictures can be seen HERE.
