Assuming every single mintmark location was different. Since it was from a master hub you do not expect ANY differences other than mintmark location. Well, maybe 80% were effevtively put in the same place, and only 20% were significant variations from standard. I could see someone coming up with about 8 varieties, and relative rarity of each mm position. The same logic of one id per die does not have to be replicated, since every die was not made from scratch like it was for early copper, right Conder? Again, I do not want to tackle to the project, but I strongly believe someone will and that person's name will be about as famous as Sheldon or Overton. Btw this is applicable to all coins up until the 90's.
