Die rotation or a counterfeit? Ethiopian 50 Matonas

Anyone happen to know a little about Ethiopian currencies? 
 

The die is rotated around 60 degrees, cannot find another example of this online.

The coin weighs 7.1 grams, and is 26.7mm in diameter.

Thank you in advance.

Hello,

It's not an expensive coin, there no reasons to counterfeit it, and your pictures are similar to those of the Numista page

N#9331

So probably a genuine die rotation.

thank you for your response, always an interesting find when it isn’t recorded somewhere on the internet already!
