This coin is classified at B among the coins ofParium, but it is alien to the series usually attributed to that mint. Somespecimens have recently been reported from the excavations at Monte Iatoin Sicily, thereby suggesting an attribution to Panormus (information fromS. Frey-Kuper). See now S. Frey-Kupper, ‘Germanicus und Drusus auf einer Münze von Panormos’, Schweizer Münzblätter 164 (1991), pp. 90-95, for the definite attribution of this type to Panormus, Sicily and its dating to AD 14-19. She interprets the coins as a half denomination corresponding to RPC 642-3, which can therefore be safely identified as Tiberius and Livia. For a metal analysis, see on Panormus, 639ff. See also Martini, Sicilia nos. 395-96, who also attributed specimens to Panormus.
