About (British) East Africa [Risolto]

For coins and banknotes, East Africa still say:
Republic (1964-date)
Isn't that wrong? I'm pretty sure East Africa doesn't exist, other than a geographical area, anymore..? Or am I missing something?
Shouldn't it say
Republic (1964)
At least for what I could read me to?

In that regard:
Should't East Africa be split up further, between Protectorate (untill 1920) and British Colony (1920-1963)? Since it is represented on the coins? Something like this:
Protectorate:
-Victoria (1837-1901)
-Edward VII (1901-1910)
-George V (1910-1920)
British Colony:
-George V (1920-1936)
-Edward VIII (1936)
-George VI (1936-1952)
-Elizabeth II (1952-1963)
Republic (1964)

"Republic" for the 1964 issues isn't really appropriate. Those pieces were issued after the constituent colonies and protectorates had gained independence but before they started issuing their own currencies. Perhaps "Independent States" would be better? We can't use "Independent Republics" because Uganda called itself a "Sovereign State" until 1967.

Should be fixed, thank you!
