So reading Haeberlin, I think I can pretty safely say that there are two separate hoards(?) with the bull-head/prow semis from Praeneste. This brings us up to 4 pieces of this type found at the site given those on display at the museum.
So first we have the one reported by Garrucci about which I blogged before. It contained the bull-head/prow semis and the lion head/ horse head as. We can call this the pre-1907 Martinetti hoard (when his collection sold). The Marinetti sales catalogue is digitized.
Second we have Stettiner pre 1893 Hoard (?) or possible just site finds. [I cannot find a digitized copy of Sangiorgi’s sales catalogue… yet.]
This contained
- bull-head/prow semis
- boar-head/lyre triens [Vecchi 2014: no. 281, other known findspot: Satricum]
- club/pentagram uncia [Vecchi 2014: no. 306, other known findspot: Pietrabbondante]
