This small billon or silver coin is the size of a solidus or schilling.
I have been unable to find the exact type in KM or Numista.
can you help, please?
The crowned reverse reads SIG III D G REX POL MDI
the weight is 0.83 grams
if you're wondering why the two sides look a different colour, it's because I can't use the Magnifier app properly. I found a YouTube video explaining how to use it but the controls seem to be for a different version.
