Caligula (ruled 37-41 AD) is one of the most known emperors of Rome. During his reign he became a cruel tyrant and was murdered after less than four years of his reign. The obverse of this silver denarius depicts the emperor in the profile, and at the centre of the reverse should be an abbreviation within an oak-wreath: “SPQR | PP | OB CS”. Although the condition of this coin is not excelent, it is very rare and valuable.
