There is no clear chronological break down of the minor variations in this issue of coins. The coinage consisted only of pennies which were cut in halves and quarters to accommodate the needs of smaller change. These cut halfpennies and farthings do turn up occasionally, but are not in particular demand as from a collectors point of view they are of much less interest than the full uncut pennies. There is no indication that any particular variety of these coins is representative of a particular event or change in mint policy, so the varieties which are listed in various catalogues are more a representation of those varieties which have been noted in publications or remarked in in auction catalogues rather than being an exhaustive list. A Copy of an English Penny of Henry III with a Dublin signature These coins were copied extensively across Northern Europe in the years following the issue.
Some copies are easy to detect as they are clearly of a different style from the genuine coinage.
Some coins are mules of Irish and English dies as in the illustration above.
