The Corieltauvi occupied a substantial territory across what is now Lincolnshire, Leicestershire, and Nottinghamshire, and their coinage is unusual among British Celtic issues for frequently displaying paired names — interpreted by most specialists as joint rulers or magistrates rather than a single monarch.

The tribe submitted to Rome under Claudius following the invasion of 43 AD, making issues from this terminal phase of their independent coinage among the last struck before Roman provincial economics displaced native gold entirely.
