Groups
A fairly easy way of organising the counterfeit shillings is separating them into groups by looking at the reverse design. The design is made up from a number of individual punches and some hand engraving. The groups are likely to represent individual die cutters although some may have used different sets of punches over time. Die links between the groups indicates either that some workshops used dies from more than one engraver or that dies from one engraver were used by more than one workshop.
