that's a good question about the chronology...which came first, the chicken or the egg?
I didn't assign a chronology to the types when I listed them, but I probably should have.
I looked it up, and most mints that issued both types (I am excluding the rocky nest, due to its rarity), started with mound first and then globe. So out of the mints that issued both types, the four most western mints issued mound then globe and the two most eastern issued globe then mound.
- Lyons ---- Mound Globe
- Trier ---- Mound Globe
- Arles ----- Mound Globe
- Rome ---- Mound Globe
- Aquileia -- Globe Mound
- Cyzicus --- Globe Mound
so out of the cities that struck both types, mound then globe was in the majority.
the other cities that only issued one type...the two most western issued mounds and the rest issued globes.
- Siscia ----------- Mound
- Sirmium -------- Mound
- Heraclea --------- Globe
- Constantinople -- Globe
- Nicomedia ------- Globe
- Antioch ----------- Globe
- Alexandria -------- Globe
so out of the mints that only struck one type, the globe was in the majority.
below are the types from Bruck. Missing is the rocky nest, because that is, as far as I know, a unique example, and Bruck only used the Vienna collection for his book.
