TI CAESAR DIVI F AVG F AVGVSTVS, laureate head right / AVGVSTI F COS DESIG PRINC IVVENT, C L CAESARES, Gaius & Lucius standing front, each with a hand resting on a round shield, a spear, and in field above, lituus right, simpulum left, X between. cf. RIC 212; cf. BMCRE 538; cf. RSC 43d. aVF. 

An interesting mule which has the obverse of Tiberius with a reverse type of Augustus. There is a spot on the reverse which could indicate a fourree (therefore, an ancient fake), however, the core appears to be silver.
