Damma - Sri Yashaditya eight pellet crown, left facing bust

Sri Yashaditya ruled Sindh in the decades immediately before the Umayyad conquest under Muhammad ibn Qasim, which reached the region in 711–712 and effectively ended the line of Hindu rulers who had issued this coinage. Dammas of this period represent the terminal phase of a silver tradition rooted in post-Sasanian imitative types, progressively abstracted over generations until the original source imagery became nearly unrecognizable.
