L. Aemilius Buca - Monetalis of Res publica Romana from 44 BC to 44 BC
L. Aemilius Buca struck a series of coins in 44 BC, in support of and jointly with Julius Caesar.

Gens Aemilia, originally written Aimilia, was one of the greatest patrician families at Rome. The gens was of great antiquity, and claimed descent from Numa Pompilius, the second King of Rome. Its members held the highest offices of the state, from the early decades of the Republic to imperial times. The Aemilii were almost certainly one of the gentes maiores, the most important of the patrician families.

The cognomina Regillus and Buca apparently belonged to short-lived families. Regillus appears to be derived from the Sabine town of Regillum, perhaps alluding to the Sabine origin of the gens. The Aemilii Regilli flourished for about two generations, beginning at the time of the Second Punic War. Buca, probably the same as Bucca, referred to someone with prominent cheeks, or perhaps someone known for shouting or wailing. The Aemilii Buci are known chiefly from coins, and seem to have flourished toward the end of the Republic.
