F2 Roman Republican Anonymous struck bronzes, McCabe group F2, Related to RRC 97 L and RRC 99 P. Irregular Luceria reverses with curved lines. 25 gram As.
The issue includes irregular Luceria style reverses, an elevated fighting platform with club, waves at keel level, and curved lines throughout the reverse (e.g. a curved keel, a curved top of fighting platform). This gives the impression of an irregular issue, but the style often matches coins with RRC 99 P mintmark and sometimes with RRC 97 L mintmark.
