I've been away from coins for most of 2022, but I did manage to pickup a rare class 6c2 penny of Henry III from the mint at Canterbury. This class is known for having very unique ornamental letters in the obverse and reverse legends that aren't replicated in other coins of the series. For this coin it is the letters C, E, and R. Some have attributed the class to the occupation of the mints of London, Bury, and Canterbury by Prince Louis of France in 1216. While I can't speak to that, it would make for quite a historical coin. An English penny struck by a French prince if you will.
