The type copies RIC 33. We have not seen the Soria coin, but it comes from the Tiermes excavations of 1993. Its provenance helps to dispel an initial reluctance to accept its authenticity, as does its variant obverse legend. The style is little guide, since it is very like that of its prototype (but the style of other Caligulan coins from Ercavica is very like that of the mint of Rome). The unexpected features are the design (Ercavica does not otherwise copy Roman reverses), the absence of any magistrates’ names and the abbreviation Ercavi (rather than Ercavica). See now F. J. Rodríguez Morales, ‘Un nuevo sestercio de Ercavica en Tiermes (Montejo de Tiermes, Soria)’, La Moneda Hispánica. Ciudad y Territorio. Anejos de Archivo Español de Arqueología XIV (1995), pp. 219-23.
