This coin weighs 4.1g. I'm pretty sure it is a Kavad I issue (2nd reign) from the PL Mint (Furat-i-Meshan). But this mint mark is throwing me off, it looks a bit like year 30, but doesn't match up as well as it should. The reverse has only one ring border, so that means the regnal year should be before Year 33 as far as I know. Any help on this would be much appreciated.
