Claudius and Nero aureus. 17.92 mm, 7.48 g. AD 50-51 resp. 51-54. Rome mint. 

TI CLAVD CAESAR AVG PM TR P X IMP PP, laureate head of Claudius right.
NERO CLAVD CAES DRVSVS GERM PRINC IVVENT, bare-headed, 
draped bust of young Nero left.

Hybrid (obv. legend from 50-51 AD, rev. legend from 51-54 
AD). BMCRE p. 173 note; Cohen (Claudius and Nero) 7; RIC 82 
var (obv. legend); BMCRE 79 var (ditto). Not in RIC, which 
suggests that the examples with this obv. legend are fake.
