"In connection with my Num. Chronicle review of von Kaenel's Claudius, I undertook a comprehensive study of the coinage of that emperor, and reached the conclusion that von Kaenel was right, against Kraay, to date the appearance of P P on all of Claudius' bronze coins not to 50 AD (Kraay followed by RIC), but to Jan. 42.
Therefore Claudius' very large issue of sestertii and middle bronzes omitting P P must all have been struck between his accession in late Jan. 41 and c. 10 Jan. 42. It is evident that Claudius' three As types, LIBERTAS AVGVSTA, CONSTANTIAE AVGVSTI, and Minerva fighting, were introduced together very soon after the beginning of the reign and were struck alongside each other first until the appearance of P P in Jan. 42, and then until the end of the P P issue probably in 43.
So there is no need for guesswork that Libertas is a very early type, probably introduced within a couple of weeks of the beginning of the reign; rather that is a very probable conclusion, supported by very strong evidence."
