1941 East Africa Shilling

This coin is genuine.
These were made from low grade .250 fine silver. The blanks were heavily acid pickled and rinsed before striking.
This had the effect greatly enriching the now spongy silver surface. As a result of the striking, the surface density was restored to somewhat near that of pure silver.

With wear, the coppery billon metal core shows through, starting at the high points, and they can become rather ugly. This coin does not show any of the sub surface billon core, which means that it must be in relatively good condition.

Over a period of decades, the silver and copper atoms migrate into each other at their interface. This is evidenced by the fact they tone more quickly that a finer silver coin would do. They can tend to look rather dirty with age.

I have only seen one East African shilling with cartwheel lustre, so one would have to assume that a substantial premium would be required to pay for an East African shilling in top condition.

The coin itself is the real Mc Coy! Of that, I have no doubt.

I can't really see a radial mint lustre, perhaps it has a very thin silver electro plating, but I am really not sure about that, even after looking at your pictures. According to Krause, no proofs were made for 1941. The type 11 reverse 'I' mintmark according to Krause, is rare. I don't know where the mintmark should appear, BUT I do notice what seems to be an 'I' in the ground above the '1' (SHILLING).

Wear wise, it seems to be very close to uncirculated. Does the edge milling seem sharp to your fingers?
Unfortunately, I have never seen types 1,11 & 111 reverses compared next to each other, so I can't comment.
