Here is what it looks like:
Issuing authority: select "Roman provinces"
Currency: select "Other..."
in field that appears "if Other, please specify": type in "Ionia - Denarius"
That's it. Then you just need to complete the file with the info about the coin (letterings, descriptions, comments, etc.).
Note: if your coin is not of roman denomination (denarius, sestertius, etc.), you can put "Ionia - Drachm" instead (then your coin would be something like
obol,
hemidrachm,
octobol, etc.). The referee will be able to validate that once your coin is submitted.
