I am helping out a friend cataloguing a coin collection, most of which is British post 17th century and so easy for me. This little silver piece is amongst it. It looks possibly Celtic or could be Middle Eastern or anywhere! Weighs 3.1g, measures 15mm across and 1.5mm thick.
Yes, I tried image search for the first time just now and got the same result: India/Afghanistan area, 800 - 1000 AD. Anyone able to be more precise?
The reverse (left side in your picture) has a horse rider and obverse (right side in your picture) has a bull. I think it's this: https://en.numista.com/19864
Thanks for that - yes that appears to be the general idea of the coin. Some listings purport to identify individual rulers, but I have not worked out how to do that yet. The bull is often described as a Zebu. Not sure who decided which was obverse and which reverse on this design! I prefer the horseman, which is why I put him first.
