The Corieltavi were a large, wealthy northeastern tribe who were highly advanced and who, according to Van Arsdell, ""used complex privy marks on their coins for die control, weight specification and perhaps even identification of metallurgical content."" Boars feature prominently on the silver units of the Corieltavi. On this issue, the obverse die is most often seen very deteriorated resulting in either a partial or even blank obverse.
