TEHRAN – A total of 23 historical coins have been cleaned and restored at a museum laboratory in the southeastern province of Sistan-Baluchestan, the deputy provincial tourism chief has said.

Dating back to the Sassanid era (224 CE–651) the coins belong to a larger haul previously recovered from smugglers or being unearthed in historical sites across the province, the deputy tourism chief, Mansoureh Molla’elahi, said on Sunday, CHTN reported.

In about 220 CE the Sasanian dynasty of Iran introduced the concept of thin flan coins, issues that were struck in relief on both sides. In order not to produce intolerable stresses in the dies, since the thinner the material the more force necessary to make it flow into the recesses of the die’s design, the depth of relief on such coins was of necessity much shallower than with earlier currency. Such techniques spread by way of Byzantium to northern Europe, where the emperor Charlemagne struck thin flan deniers (small silver coins), or pennies, which became characteristic of both his own and neighboring kingdoms.

In many ways, Iran under the Sassanian rule witnessed tremendous achievements of Persian civilization. Experts say that the art and architecture of the nation experienced a general renaissance during Sassanid rule. In that era, crafts such as metalwork and gem-engraving grew highly sophisticated, as scholarship was encouraged by the state; many works from both the East and West were translated into Pahlavi, the official language of the Sassanians.

The Muslim conquest of Persia, also known as the Arab conquest of Iran, led to the fall of the Sasanian Empire of Iran (Persia) in ca. 651 and the eventual decline of the Zoroastrian religion. The rise of Muslims coincided with an unprecedented political, social, economic, and military weakness in Persia.

The conquering Muslims at first mimicked the coinage of their predecessors. In the western provinces, they issued gold and copper pieces imitated from contemporary Byzantine coins, modifying the cross on the reverse of the latter somewhat to suit Muslim sensibilities. In the eastern provinces, the Arab governors issued silver dirhams that were copies of late Sasanian coins (mostly of those of Khosrow II; with the addition of short Arabic inscriptions on the margin and often the name of the Arab governor in Pahlavi; even the crude representation of the fire altar was retained.
