Sind was the first part of India to come under muslim rule. The earliest Amirs issued small silver coins (1/4 dirhams) - all carrying the name of the Amir, but without any dates, so they are very difficult to date exactly, especially since the Amirs of Sind are virtually unknown from other sources. These coins are generally not rare, but are difficult to find in high quality, like this coin.
