Alright, I've been sitting on this guy since I went to my last coin show...in January! And I just don't trust my IDing (since I cannot read the language I'm just looking for patterns in squiggles and curves). Here's what I've got... It's a silver drachm of a western satrap. The reverse shows 3 arched hills and a river with a crescent moon and Sun within. Writing in ancient brahmi. And I believe it has a thunderbolt. I think it's Viradaman?... But that is a very uneducated guess in this area (this is my only coin of this type and there are many). It's 15 MM of western fury. Any idea who the satrap is? While we are at it please post your western satraps or anything you deem relevant!
I think it's Rudrasimha II but this is waaaaaaay out of my area. CoinIndia is the site to learn about these. They even break down the script. Zeno.ru is a good place too. http://coinindia.com/galleries-rudrasimha2.html
I had my own run in with one of these guys and it was @THCoins who helped me out. Damajadasri III Sorry I'm no help otherwise. -d
Agree with Rudrasimha II, son of Jivadaman. Look here: http://www.worldofcoins.eu/forum/index.php/topic,30883.0.html
