A fifth Cork groat of the readeption of Henry VI – Oisín Mac Conamhna and Jack Pope

Very recently, one of us wrote about the four Irish groats then known from the second reign of Henry VI, all from Cork, in the political and numismatic context of the contemporary earldom of Desmond. Even more recently, the other of us has acquired a fifth newly-found specimen of this coinage. The purpose of this note is to record and describe this addition to the corpus.
