Sorry, Denarii. Barbar seems to refer to Denarii minted by barbarians? but the AI result didn't come up in English?
Ps And don't call me Barbar.
Barbar, likely short for barbarus which in this context likely means foreigner. It can also mean cruel, uncivilized or savage but I'm taking the not-roman approach here.
I'll add "unable to understand context" to my list of frustrations about LLM usage.
