I've just finished up cleaning a group of minims that are reportedly from a single site in Suffolk. I will be taking the lot to be recorded by PAS once the seller lets me know a more accurate find spot. Interestingly, some of the coins are very very similar, perhaps even die matches. The prevailing style of the radiate crown is 'sawtooth', with the radiations parallel to each other. The reverses, on the other hand, vary greatly in their artistic quality and style.
Here are 3 coins, struck from the same reverse die, presumably at the same time by the same team, given the high consistency of the strike. Other coins in the lot might be from the same die too, but with such a small area of the die on each flan (these coins are 6mm across), I could not satisfactorily place any more into this group.
My question is: what is the headwear on this figure? I would presume a modius, but I could not find a parallel in the coinage of the Gallic empire (Serapis being a rare reverse with a full width modius at the top of the head). It appears to be a single line out from the top of the head that is then cross at the top to form a T shape.
I have identified a further 3 coins with matching reverse dies in the lot, but they are not in such nice condition.
I thought I'd also show off this minim from the lot, which shows Mars (this one is 7mm across). Here, the headwear is poorly copied from an official type, where it seems the die sinker has not understood what the coin was depicting. A full flan strike of a very similar design shows what the whole design could have looked like, and I've included examples of official issues to show how this design changed from roman helmet to farmers hat:
