Hi, I only mentioned the leper colony in Addis Ababa because I know of its existence, having been there. I do not think there are any coins or tokens associated with it. They produced woven cloth and wicker products for sale, which supported the institution, perhaps they still do. It is called the Korah Leper Colony. There are others in the country.
Michener wrote about the Hawaiian leper colony and its priest/founder in his masterpiece, "Hawaii." Worth a read.
Thanks for answering! Sorry for misunderstanding you! If you've visited Ethiopia: Perhaps you have any knowledge about other tokens from there?
