How to Identify the Denarius of C. Cato

Begin with the reverse, which is the decisive feature. Look for Victory driving a biga, a two-horse chariot, galloping to the right; she holds the reins in one hand and a whip in the other. Below the horses, in the exergue or lower field, find the moneyer's signature C·CATO. That name is what separates this issue from the many other Republican denarii that also show Victory in a chariot. If you cannot read a signature, compare the letter forms carefully before attributing the coin.

Turn to the obverse to confirm the period. It should show a helmeted head of Roma facing right, with the helmet plumed or winged in the second-century BC style, the legend ROMA, and a mark of value near the chin or behind the head. Roma's helmeted profile is standard for denarii of this date and, combined with the C·CATO reverse, pins the coin to the 123 BC issue catalogued as Crawford 274/1.

Check the physical characteristics. This is a small hand-struck silver coin, generally about 17 to 20 mm in diameter and weighing roughly 3.7 to 4 grams. Expect an irregular flan, some off-center striking, and natural toning; ancient dies were cut by hand, so no two examples are identical and minor style variation is normal rather than a warning sign. A coin that is perfectly round, unnaturally uniform, or the wrong weight deserves scrutiny.

Watch for look-alikes and modern reproductions. Victory-in-biga denarii were struck by numerous moneyers, so always read the name rather than relying on the chariot scene alone. Be cautious of cast copies, tourist replicas, and coins with tooled or smoothed surfaces; casting bubbles, seams on the edge, a soapy texture, or a suspiciously light or heavy weight are red flags. For any meaningful purchase, buy from a reputable dealer and, if in doubt, seek an opinion from a specialist in ancient coins.
