The focus of research are coin types issued by two local mints in the province of Thrace ‒ Pautalia and Serdica. Located in the western part of this Roman province, the two cities struck prolific coinage, starting in the second half of the 2nd century until the early 3rd century (with short interruptions within this period). The mint of Serdica went on to strike a restricted volume of coins also under the sole rule of Gallienus (260-268). A thorough analysis of the two coinages reveals several rare coin types, some of them apparently unique within the Roman provincial coinage. A part of these coin types reflect religious beliefs of the local population, while others demonstrate the impact on these two provincial cities of the Roman imperial cult, as well as its reception and expression in the local coinage.
