To Hrefn's point, we sometimes get cataloger mistakes heaped upon mistakes. Tell me if you agree: the attribution on my newly-arrived Valentinian II solidus to RIC IX 69a by the auctioneer and the prior attribution to RIC IX 46c2 (on a prior dealer tag that was included with the lot) variously omit the rosette diadem on the obverse bust or the lion heads decorating the throne on the reverse. I say it's RIC IX 46d2.
Yes! I'm splitting hairs... Getting the correct attribution is not easy. Using RIC IX is sweet sorrow, with its myriad codes, references to other entries, and scant photographs. Here's how I break it down:
Valentinian II only appears in period III, IV, V, and VI (375-392 AD), but no coins were attributed to him in period III and no gold coins in VI, leaving only period IV and V. For period IV, the obverse legend D N VALENTINI-ANVS P F AVG matches code (2c). The rosette-diademed bust matches code (B). The reverse legend CONCORDI-A AVGGG H and type matches #46(d)2, presuming the lion heads throne. That’s not a million miles away from the earlier attribution to 46(c)2, which does not capture the rosette diadem, but does recognize the lion heads on the throne. The auction attribution to RIC IX 69(a) doesn’t capture the lion heads or the rosette.
