Is this coin authentic? Somalia 5 shillings 1970

Hello all. Recently bought this coin from a local dealer. Needed a little help in ascertaining if this coin is authentic. Sorry if the quality of the pictures is not up to the mark( this is the best my mobile camera could do).
Thank you.

Diameter and weight?
Why do you think isn't good?

Looks alright to me. The coin on that page is a browner colour for some reason.

​Diameter 38 mm and weight is 27.3 gm.
The tone and the sharpness of the features looked off to me at first glance.

​Yes. The colour of the coin was the first reason I doubted it's authenticity. Also the features of the coin are very sharp.

nickle metal takes on all sorts of surface tones under various environmental conditions, after decades. the color variation is not surprising or even interesting.

Não se julga um metal pela tonalidade! A moeda em si é reconhecida oficialmente. Só pesquisar : existiu a 2 conferência em 1970? O peso diâmetro ,borda e designer confere? Isto sim e fazer uma boa avaliação e dar uma opinião sobre a peça.
