This work focuses on the coin finds from a Roman auxiliary fort situated in the province of Dacia (AD 106-108), more precisely Dacia Porolissensis (AD 119-275), which was located on the border of the village of Buciumi (S?laj County). The fort was systematically researched between 1963 and 1976 and is one of the best-known of its kind in Romania. 477 coin finds are discussed in this volume, 462 from the excavations of this auxiliary fort and 17 from a private local collection that were also found in the fort area. This study is of high importance because the coins allow the dating of the archaeological contexts within the fort starting from the 1st phase of construction up to the last phase of existence. The results provide specific contextual information on various important features within the fort: the precinct (gateways, corner and intermediary towers), the headquarters (princAia), the commanders house (praetorium), the inner baths and other buildings. The coins are fully catalogued and illustrated.
