A less thorough but still comprehensive analysis is found in Historia Nummorum Italy, a text published in Britain in 2001 by a group of numismatists coordinated by Keith N. Rutter.
Other sources of cataloging are the Sylloge Nummorum Graecorum; generally the most recent or most widely available are used, such as that of the American Numismatic Society, Copenhagen, and France.
The territory of Suessa, in pre-Roman times populated by the Aurunci, came under the rule of Rome, which established a colony there under Latin law, in 313-312 BC.
In 209 B.C., during this very conflict, twelve colonies, including Cales, sent legates to Rome, where they refused to give the aid that had been requested of them according to the formula togatorum.
In the period between the First and Second Punic Wars, new coins with similar characteristics appeared in a group of cities linked to Rome.
The cities share not only types but also coins and some identifying marks, such as the recurring acronym ΙΣ.
[23][24] These coincidences, together with the simultaneous presence of coins from these cities, in the treasures that have come down to us, alongside those from Neapolis and Rome, stylistic congruities and other elements, have led scholars to speculate on some form of common circulation and the existence of a supra-civic authority to control coinage.
that minted their own silver coinage, a stater (or didrachm) of Campanian foot, weighing about 7.5 grams and divided into two drachmas.
This foot was used throughout the Campanian coast, from Velia and Poseidonia in the south to Cumae and Neapolis in the north.
Sambon lists several of them: lyre, triskelion, crescent, tip of trident, sword, pentagon, shield, Phrygian helmet, owl, lion's snout, tripod, spearhead (or leaf), trophy, thunderbolt, eight-rayed star, wing, shell (of pecten), two-handled vase (or cantharus), helmet.
[31] Three main groups of bronze coins were minted in Suessa: the one with Minerva/Gallus, the one with Apollo/man-headed bull, and the one with Mercury's head on the obverse and Hercules strangling the lion on the reverse.
The last type, with the head of Mercury (or Hermes) on the obverse and Hercules (or Heracles) on the reverse, is specific to Suessa.
[38] The head of the goddess, depicted on the obverse, is turned to the left and wears a Corinthian helmet with a long hackle.
The type depicted on the obverse is similar to that of the quincunx from Larinum[39] and Luceria[40] as well as other coins including Roman litra.
Coeval coins from Neapolis show the same type, with Apollo on the obverse and the bull on the reverse.
Based on the findings, the area of diffusion, apart from the dubious Strongoli treasure, is central Italy.
[46] The legend ΠROBOM found on the Mercury/Hercules bronze has the letter Π with a shorter right vertical bar, .
