The third coinage of Edward III, usually referred to as the Florin coinage, is a complex issue particularly so in the case of those coins produced at the Durham mint. This article focuses on a particularly puzzling reverse die, the VILA or Villa die, which has been shown to have been used in the period 1348 to 1351 towards the end of the series. The author has identified two VILA dies, described how they can be distinguished and produced a corpus of the coins known to him.
