Roman, minted in Rome

Aureus (Coin) Portraying Emperor Otho, A.D. 69 (January/April), issued by Otho

Diam. 1.9 cm; 7.25 g

Gift of Martin A. Ryerson, 1922.4865

The purpose of the first portrait coins was to identify the ruler. The front side became a mirror of the sovereign’s self-image. The back was often used to communicate the ruler’s accomplishments or intentions.

The profile portrait was used because it suited the very shallow depth and limited surface of the coin. The tiny images were carved by engravers into bronze dies, one for the front and another for the back. Whereas modern coinage is cast by pouring molten metal into molds, these coins were struck, one by one.


The primary purpose of portraiture was to create an accurate likeness of the subject. During the three-month rule of Otho (r. A.D. 69), he issued two coins. This coin shows him at his real age, sixty-eight years old. The other coin, not pictured here, shows him as a more vital younger man.
