228-Zimbabwe samples

There is no such thing as a genuine mint, unused, African plate. There are some collectors who specialize in African plates and they can testify that genuine, used African plates are always in fairly poor condition.
These Zimbabwe plates were originally sold by German Ebayers. These plates have undoubtedly never been near Zimbabwe.

Similar mint samples are also known from Ghana, Lesotho, Liberia, DR Congo and Cameroon.
