摘要：This paper is based on the study of Roman silver coins, from archaeological sites located in Roman Dacia and Pannonia. Initially centered on the record of hybrid silver coins, the paper expanded its analysis on counterfeit pieces as well in order to fully understand all problems of Roman silver coinage from the 1st to the 3rd centuries AD. The new and larger area of research had more than one implications, coin distribution on the studied sites, influx of coin in the province, quantity of recorded counterfeited pieces being just some of them. Thus every situation was discussed in different chapters, first presenting the coins and the laws that protected them, the studied sites and the analyse of the silver coins on these sites, the general and compared situation between the provinces, interpretation of the counterfeited and hybrid pieces and finally, conclusions on the subject. All these tasks have been achieved one step at a time, each archaeological site providing precious data which piled up and was finally pressed in order to present the correct historical situation.
