Nepalese mohur?

Hey guys, I'm new to the forum. Ive been using this site as a reference for a while now. I recently came across some Nepalese mohurs and was unable to identify this one. Some help would be very much appreciated.

Thanks

The coin is the size of a 1 mohur

Hi,

Is 820 a miss type? i found the coin on this website as well http://www.snowlandcoins.com/nepali%20coinage.html and its listed as 1700.  Didnt think it was that old
 
Also numista has the coin listed under Nepal - Mohar (1546-1932)

Using this website http://www.collectionstudio.com/en/datescalculator/nepal/ i managed to translate the numbers and it ended up being 663. Any ideas?

I found it here http://www.ngccoin.com/price-guide/world/nepal-kingdom-of-patan-mohar-km-320-820%281700%29-cuid-108433-duid-280315

It says 1700. So im not sure where the 820 came from?

It's Nepal Sambat Date 820 (1700 AD) KM#320.

Numista Calendar Does not have an entry for NS. Maybe we should have it added there.
