The subject of the study is three Roman provincial coin hoards, which were unearthed during excavations conducted by the Univercity of Thessalonike at the site of Dion in Macedonia in the years 1998, 1999 and 2000, respectively. Their concealment in the same area, as well as their very similar contents and burial date, indicate that the three finds are clearly related nad they are therefore discussed here as a whole. Their interest lies both in the secure archaeological context from which they derive and in the large number of coins they include, something that is very unusual for Roman provincial hoards. The aim of this publication is double. The first is to provide a detailed presentation of the new material and to discuss its contribution to our knowledge of individual issues. The second is to attempt an interpretaion of this evidence and to place it within the general context of other Roman hoards from Macedonia and the Balkans.[...] (Από τον πρόλογο του βιβλίου)
