Hi
Grills are confusing. Points are very difficult to make out. I've scanned this stamp to get a better view of the grill in order to count the number of rows. I counted 14x16. Is there a reliable way of enhancing the grill in order to make a better identification? I read somewhere that rubbing graphite onto the stamp will improve visibility of the points. Is that recommended by experienced collectors?


I tried to crop the grill image even closer but detail is reduced to the point of being useless.
