Tiberius, with Caligula as Caesar AE "As" 30mm, 15.65g 35-37 AD C CAESAR TI N QVINQ IN V I N I C , Bare head of Caligula left TI CAESAR DIVI AVGV F AVGVSTV P M, Laureate head of Tiberius left RPC I, 182 Contrasting the expansive series of coins minted in honor of Tiberius' original heirs Germanicus and Drusus, Carthago Nova was the only city to mint coins for Gaius Julius Caesar--better known to us as Caligula--as the heir of Tiberius. Three denominations were minted - the 29mm "As", a 23mm of unknown value, and an 18mm "Quadrans". All three are quite rare coins - perhaps only 150-200 specimens are known across all denominations, with RPC 182 being the most common - 59 specimens on RPC online, and 36 on ACSearch, with at least some duplicate entries for the same coins sold multiple times. After the banishment and death of Nero and Drusus, Caligula's older brothers, the elderly Tiberius was in desperate need to secure a plan of succession. Despite the immensely bad blood, in 35 he adopted Caligula and his own biological grandson Tiberius Gemellus, and brought them both to his estate on Capri, where later authors claim various sorts of abuse. Due to the isolated environment, exactly what happened is a matter of debate, but Tiberius died in 37 and although his will decreed that the empire should be split between his two heirs, Caligula was able to seize absolute control, keeping Gemellus in the subordinate position of Caesar until he was arrested and executed later that year on suspicion of treason. Feel free to post anything related! Also, I am not able to find an explanation online of the explanation of the titulature of Caligula's side - I got "Gaius Caesar, Tiberius N? Five" and I'm lost after that. Any help appreciated!
