Summary
[edit]DescriptionRoman coin (head of Caesar Augustus) 1.jpg |
English: This is a ~2040 year old, one denarius silver coin issued by the Roman Empire. The portrait depicts Caesar Augustus (real name: Gaius Octavian), the first emperor of the ancient Roman Empire - he ruled from 27 B.C. to 14 A.D.
This coin was produced at the Caesaraugusta Mint in Spain (= modern day city of Zaragoza) in 19 to 18 B.C. The flip side depicts a comet that appeared in the year 44 B.C. The pit on the cheek is a "banker's mark", which was made to test the legitimacy and solidity of the coin (fakes were made in ancient times). Identification: Augustus 37B of "Roman Imperial Coinage, Volume I", Second Edition See info. at: en.wikipedia.org/wiki/Augustus and en.wikipedia.org/wiki/Denarius and en.wikipedia.org/wiki/Caesar%27s_Comet |
