CALIGULA, A.D. 37-41. AE As (10.69 gms), Rome Mint, ca. A.D. 37-38. NGC VF, Strike: 5/5 Surface: 2/5. Smoothing. RIC-38. Obverse: Bare head left; Reverse: Vesta seated left on ornamental throne, holding patera and scepter. Deep mottled green and brown patina. Smoothing is evident on the fields, but the piece retains a strong portrait of Caligula and a well-struck depiction of Vesta. A wonderfully appealing example of this always-popular type featuring perhaps the most infamous of the "Twelve Caesars".
