Damma - Sri Yashaditya Cachas

Sri Yashaditya was among the last Hindu rulers of Sindh before the Umayyad general Muhammad ibn Qasim invaded in 711–712 AD, ending roughly a millennium of continuous Hindu and Buddhist rule in the region. The damma denomination itself was a small fractional silver unit that persisted through the Arab conquest and was later adapted by the new Islamic administration — the type survived the regime change even as the political order collapsed around it.
