'These two lists are then followed by a third list, more relevant here, of ‘These Coines I found wth Sr Phil: Morgan att Ruperra Sept 8 1645) in Glamorgan Shire’. Ruperra Castle, just to the north-east of Cardiff, had been built by Philip Morgan’s father, and, although I have not found any evidence that Ussher paid a visit, it is not unlikely since we know he was in the vicinity at that date.
Therefore, it seems probable that ‘I’ here is Ussher, and that this is his own little catalogue of the coins he saw there. The list of 16 coins is, however, in a very jumbled order, ranging from Trajan to Decentius (second to fourth century AD), and ending with a papal coin of Paul III and an incomplete entry for a coin of Ethelred. There is an occasional mistake, such as Solonina (sic), but the entries are accompanied by dates and brief historical notes, showing a well-informed historian, and one interested in dates and chronology.'
