Can someone tell me what this coin says?

Friend inherited it from her stepmother. Insights would be much appreciated. Thank you.

The image is inverted:

and we really need both sides. Date: AH 1316. 

EDIT: Oh, this is a seal, not a coin, right? So, the original image is fine, but of course the script is inverted if it is a seal.

I read:

رضا فلى 
١٣١٦

Name sounds perhaps Urdu??

Ah. Thank you. I was thinking maybe farsi but from mumbai?

I actually hesitated about the date because of the shape of the “6”. It does suggest a Persian origin ─ or at least an eastern origin (hence my Urdu suggestion, not just based on the name).

Example of Google Image search. Perhaps “signet ring” combine with “islamic” or “muslim” would be productive?

Great idea. Thank you! 
 I tried Google  lens but maybe a search is better. I live in an area with a lot of Iranians who speak and read Farsi so I am also going to ask them to translate.
