1956 Sudanese 1 millim

I think this is an attractive little coin. It's actually one of my uncle's. I've very slowly been cataloging his coins for him, and I'm at the tough end of it. It's tough because I've saved all the hard ones for last--hard ones like this. They are ones I can't read and don't have a very accurate guess on attribution, so I just have to root around in my books or online until I figure out what it is. There are also some that I can identify, but I'm afraid to hazard a guess on the grade, or I have a question about, and want to research a little more.
