Aes Formatum Looped arc; curved bottom; simple sides

Aes formatum — pre-monetary cast bronze of the Italian peninsula — predates Rome's introduction of struck coinage and functioned as weighed metal rather than currency in any modern sense. These pieces were not manufactured to a standard; they were cast in rough forms and exchanged by the scale. The looped arc with curved bottom places this among a morphological type associated with central Italian production, though attribution to a specific region or workshop remains largely impossible without associated find context.
