I'd appreciate some help from those familiar with such coins. The first coin was identified by it's previous owner as per the title but confirmation would be useful. As for the other two, there's nothing that I'm familiar with to even allow a guess at the country. Thanks in anticipation.
1. Habbarid of Sind, Dhamma 870 - 1009ad? Silver, 10.5mm, 0.6g.

2. Silver, 12mm (irregular) 0.9g.

Non illegitimis carborundum est. Excellent advice for all coins.
