Like Father, Like Son

I believe the seller had it right. I think it is Constantine II RIC VII 237 London variant because of the reverse break. Both are very nice coins for sure, but I prefer the London style.

Two very nice coins, I perfer the London mint one.

Wow Doucet => those are gorgeous!!

I don't have any Londinium coins yet. That's next on my list.

I do have a somewhat odd die variation of Constantine II. I'm planning on purchasing a usual die version later on.

Nice coins. I don't have this type in as good condition as your two coins.

I find it interesting that my coin is the left facing version from London and RIC 287 (directly under Doucet's right facer) but look how different the helmets are. More, the Trier example is closer to Doucet's than the two Londons are to each other. I wonder if we gathered 100 of these two London RIC numbers how many would have similar helmets and how many would be yet different?

We will never know how many cutters worked in one mint or, with certainty, even how many worked on one die. When you see things like this you have to think they were trained by the same master if they were not done by the same hand. I seriously doubt any cutter in this period did both obverses and reverses and suspect there were lettering specialists as well as portrait cutters so there could have been a team involved on every die. It is also possible that one cutter did everything on one die but I suspect this is more likely at a mint with smaller output than all of the Constantinian mints seemed to produce.
