Lousy photo, sorry. Rhodesia 20 cents 1964, KM#3. If memory serves me correctly this was the first coin to feature the Machin portrait.
Zanzibar riyal, Barghash ibn Sa'id, dated 1299 AH (1881-1882) although struck at the Royal Belgian Mint, Brussels in 1883.
South Africa is very OK. I suspect that is a half penny there...so I will post another African coin...2012 Zambia 1 kwacha
