Signet Ring Egypt 1960s hallmarks

Hi,

I got this ring from my grandpa who bought it at a street market in Cairo in 1961/62.

There are three stamps next to each other, of which I identified two: Ibis bird and date letter (60s). There's also an additional stamp, I think its the fineness mark but I don't understand what it says.

I'd appreciate your thoughts. Thanks!

 

Hello Dom.
Could you put the ring down on a plain background (f.i. piece of white paper) and photograph the marks like that please? On your current photos I see mostly fingers and background and only very tiny marks.

 

Looks like a high carat goodie- Egyptian gold can be 18-21K. American jewelry (14K) always looks rather cheap to me, not that I'd ever turn down free gold.
