Nearly all the Kenyan coins have the coat-of-arms side with the denomination as the obverse and the portrait side as the reverse. But the descriptions with letterings are switched! https://en.numista.com/catalogue/pieces4689.html
So which parts should be changed? And which side was designed by Norman Sillman?
There should be a feature when you use the option "switch obverse and reverse picture" that it's also possible that the texts get switched (yes it's a comfort feature but in this case great comfort)
Look at the catalogue reference indicated on the listing; it is K&M so in order to maintain consistency the Numista catalogue should follow K&M format which is that the obverse has the arms (usually) and reverse always has the busts.
Just because you can't see it ... doesn't mean it isn't there - Anon.
Usually local national banks decide themselves which one is obverse and which is reverse.
But as this information doesn't given at Kenya`s national Bank site, we can follow KM #.
