This is one of the first Groats with trefoil-pointed cusps. At this point, these are exclusive to the Perth mint and it is not until some way into the series that there is a first die-link with Edinburgh. It would seem that they were struck by a separate moneyer while the old tri-pellet Groats were still being struck in Edinburgh by Bonagius. This obverse die was originally used without the trefoil on the breast - this was added later.
