This book prepared on Byzantine Coins of Çanakkale Museum includes an evaluation of the coins documented. Covering the Hellespont, the ancient name of the narrow passage between the Aegean Sea and the Sea of Marmara, it is a significant geographic location in the production-consumption and shopping relationships between these two regions as well as between the Black Sea and the Mediterranean regions at the long distance in the Byzantine Period. Written data indicate that this location maintained its importance in the early, middle, and late phases of the Byzantine Period. Due to a paucity of archaeological research on the upper and middle sections of the strait, a project on the Hellespont was set up in 2004. Archaeological surveys were conducted in the lower, middle and upper parts of the strait and in the Gulf of Saros, where data from the Byzantine period are scarce. In parallel with these studies, the Byzantine period artifacts in the Çanakkale Archaeological Museum were also evaluated.
