Aes Grave Triens, Thunderbolt & Dolphin, Crawford 14/3

Anonymous Æ Aes Grave Triens

Thunderbolt / Dolphin – Cr 14/3

289 - 245 BC

Anonymous Æ Aes Grave Triens (= 4/12 or 1/3 of an As); the coin was cast in Rome (according to Crawford, Thurlow & Vecchi and Rutter) or Campania (according to Sydenham), the period of minting ranges from circa 289 BC for heavier coins to about 245 BC for lighter coins. The obverse has a thunderbolt and four pellets. The reverse has a Dolphin swimming right and below are four pellets. T&V comment that the thunderbolt is an attribute of Jupiter, the chief god of the Romans and the dolphin is an attribute of Neptune. The coin weighs 94.91 grams and has a diameter of 49 mm. A small piece of the coin is missing. The reverse is at 10:00 relative to the obverse. The coin was graded VF with a light brownish ‘Tiber’ patina and came from a private German collection. Attributions for the coin:

·         Crawford, Roman Republican Coinage - 14/3 – Crawford gives the 14 series As a weight standard of 322 grams for this series. Three times 95 = 285, which is a bit below the weight standard, but well above the 267 gram average for the 85 examples of Cr 35/1 I found.   

·         Thurlow & Vecchi, Italian Cast Coinage – 3a - The weight of the coin places it in the later period by T&V and thus the “a”.

·         The coin is not in Grueber, Coins of the Roman Republic in the British Museum. It is listed in BMC Italy and is on the British Museum web site.

·         Sydenham, Aes Grave – 38; Coinage of the Roman Republic – 10

·         Sear – 538

·         Rutter, HN Italy 270

·         ICC 27

·         Haeberlin pp. 95-97, 1-160 pl. 39, 6-14
