The coinage of the Sasanian Empire (224-651 CE) is not only the most important primary source for its monetary and economic history, but also of greatest relevance for its history and art history.Coin hoards are of pivotal importance for studying Sasanian coinage. On August 29,2007,two jars were unearthed during the construction work for the new border sentry post of “Havār-Barxāh-loh” in the Piran-Shahr region (close to the frontier village of Tamar-Chin, about 35 kilometres away from Piran-Shahr).The work was carried out by military personnel belonging to the frontier guard’s regiment. The jars  contained altogether 1267 Sasanian silver coins, mostly from the Khusro II (590–628) period. Also numerous drachms of Khusro I (531–578) and Ohrmazd IV (578–590) were present, as well as a few late pieces of Ohrmazd VI, Queen Azarmigdukht, and one early Arab-Sasanian drachm.
