Obol Simmering and Réte Type

The Boii occupied a vast swathe of central Europe before Caesar's Gallic campaigns and Dacian pressure from the east combined to shatter their political coherence by the mid-first century BC. The "Simmering and Réte" classification groups a cluster of small silver fractions sharing die-linked characteristics first systematically documented through hoards found in the Vienna basin and southwestern Slovak sites — Réte being one of the key findspot assemblages used to anchor the typology.

At 0.69g, these sat at the lowest functional denomination the Boii struck in silver, likely used in small-scale exchange rather than tribute or inter-tribal payment, which tended to involve larger module pieces.
