C. Antestius Moneyer of the Roman Republic from 146 BC to 146 BC.
C. Antestius was a moneyer for the year 146 BC. He is not otherwise known, but many of his coins feature a puppy or dog on the design.

Gens Antestia, or Antistia, was a plebeian family at Rome. The first of the gens to achieve prominence was Sextus Antistius, tribune of the plebs in 422 BC.

The oldest families of the Antistii used the praenomina Sextus, Lucius, and Marcus. In the later Republic, members of the gens also used Publius, Titus, Gaius, and Quintus.

In 29 BC, Octavian elevated this family to the patriciate.

Moneyer's ancestor was supposedly rescued from shipwreck thanks to persistently barking dog. For that reason dog appears on every issue of this moneyer. Moneyer's family came from an ancient town Gabii in Latium.
