Unknown Arabic coin [Resolvido]

Not sure where to start looking for this one. I can see what looks like 3 and 7 at 8 o'clock on the obverse(?), but after that I'm lost.

Any pointers?

Well, I'll be... I found it! It is a 1 pice coin from Bengal, 1831 (Year 37 of the reign of Shah Alam II).

The Numista search feature is pretty great. I just put in diameter 22-23 mm (my calipers read 22.7 mm), round, copper, and for the Gregorian year I guessed it was pre-20th century and just put 1000-1900.

I love this website!

The regnal year 37 is frozen. These coins were minte over a period of several years.

This site is indeed very fine and usefull.
Thanks to all users

So if the Shah died in 1806, why was this coin minted in his name in 1831?

The coin says: 'In the name of Shah Alam'.....
