A wonderfully clear and well centred strike. I can't be of any help in this area, but I know a good coin when I see one. The characteristic toughras - I had not seen them before you started showing them - are an interesting and lively aspect of these series. Maybe they were part of a development from normal writing to a stylised, highly formal shape...
