Silver Minim - Regni Chichester Half Horse

The Regni Chichester Half Horse minims are among the smallest silver coins ever produced in pre-Roman Britain, struck in the decades immediately preceding the Claudian invasion of 43 AD. The Atrebates, who had strong Continental ties — their dynastic origins lay with the Belgic Atrebates of Gaul — operated a relatively sophisticated mint network for the period, centered around the Chichester region.

At 0.25g, these pieces were genuinely functional fractional currency, not ceremonial objects. That they survive at all owes largely to metal-detector recoveries across West Sussex.
