NOT IN RIC
UNLISTED ISSUE. RIC does not list issue with mintmark pattern PAR. However, Bruun mentions in footnotes few coins with irregular m.m. QAR, SAR, PAR (cf. p. 261, 263). Probably most coins with m.m. PAR should be regarded as ancient imitations. But some of them may belong to the official unlisted issue.
The specimen in question seems to be an official mint product. Listed in Ferrando (p. 180, no. 765). Should be listed after issue erroneously attributed as THESSALONICA 84-87 (see CORRIGENDA, VOL. VII, p. 508) and before ARLES 208.
