I’m still re-reading/skimming my way through the physical book:
Lo Cascio, Elio. “Credito e moneta nel mondo romano.” In Credito e moneta nel mondo romano. Edipuglia, 2003.
And this isn’t at all relevant to my current line of thought but wow is it fascinating!
I think it is super interesting that the coins are made at the time that the mint was experimenting with returning to IIIviri (moneyers):
This reminds me of coins with long highly abbreviated inscriptions presumed to correlate to public monuments on the republican series also references to the purpose of the coinage and the reference to public funds.
The form of the cippus as reverse type is also fascinating as a means of taking a monumental text and circulating. There are more examples, all the relevant ones seem Augustan.
Inscriptions on Cippi on Augustan Coins (all c. 16-12 BCE):
IMP CAES AVG LVD SAEC
IMP CAES AVGV COMM CONS
S P Q R IMP CAE QVOD V M S EX EA PQ IS AD A DE
C C AVG VS TI
