After the Bishopric of Paderborn was reorganized in 1231, Driburg became the seat of an archdeaconate. The "Driburger Pfennig" began to be minted at this time, and has now become a very rare coin (see "Coat of arms" below). It was also at about this time, or perhaps somewhat later, that Driburg was granted town rights. The document granting them, however, was lost long ago. A document from 1290 nevertheless makes it clear that, by this time, Driburg has town rights.
