Persian.

In this case is a collection of Persian coins, very choice, and of no mean workmanship, and, of course, portraying the faith and rites of the fire-worshippers. One era is distinctly Greek in style, and marks the period of Greek supremacy. The oldest gold coin known to the collector is the gold Daric of King Darius, with the head of the king in bold relief; and all Persian coins are so called in remembrance of this monarch. Their money was very fine, so the word Daric has become incorporated into numismatic terminology to designate any pure gold coin. Nos. 58 to 67, inclusive, of this series, are silver coins of the Sassanian kings.
