In my Satricum post I note that Termeer and Prins 2021 observed there was found:
“one Lion bronze (no. 38) with reverse lion to the left is a variety of RRC 16/1a and 1b, only known from Vicarello and Carsoli”
I made a note in my copy of RRC of the new subtype and moved on, now today while reading Catalli 2014 on the Nemi finds (scan on file), I notice that there too a lion left was listed there among “rinvenimenti soradici” stray finds from the sanctuary area.
How amazingly odd to have a sub-type that keeps turning up well provenanced, but with almost no presence in trade. Of course, Schaefer knows of one such specimen that sold in 1990, but I can find no more with a quick search of the usual databases.
