This image is made from a scan of a black and white engraving printed in a book from te 1840s.
The picture shows two sides of a coin, as if there were two coins lying side by side joined by a thin strip of paper. On the left we see a man’s head, crowned with a laurel wreath to show he was the Roman emperor, or Cæsar. He has a rather implausibly long neck and is clean-shaven with curly hair.
Writing around the coin identifies the portrait as of Claudius.
The coin has a beadwork edge but has been stamped poorly, so that the beadwork is not actual at the edge of the coin.
The right-hand part of the drawing shows the other side of the coin, featuring a two-wheeled chariot with two people standing in it, or possibly one person and a goat. The chariot is pulled by four horses. Writing on this side of the coin identifies the ruler as being “of Britain” (De Britannis).
