For this reason, special money was made to circulate in the colonies. (Except the USA colonies (or leprosariums) which used regular US currency). Some of these leprosy colony moneys were government issued and some are considered privately issued tokens today. There is a lot of interesting reading on the subject here at CT & I will post some of the previous thread links. If you visit all the links you will find more photos of these historic Leprosy colony coins/tokens & learn about other Leprosy colony locations around the world. There were a few compelling reasons for issuing special money at the colonies. (1) It was obviously an attempt to keep the area government money out of the hands of the inmates. (2) It made it difficult for inmates to purchase things like rum from the black market dealers. (3) It also made it difficult for an inmate to save up cash and orchestrate an escape.
