There are two types of Kruger coins: "Single Shaft" and "Double Shaft", which is derived from the wagon depicted in the Republic's Coat of arms. The "Double Shaft" coins are known by the nickname "Disselboom", which is Afrikaans for "Double Shaft". The 1892 "Single Shaft" pond coin is a unique coin. The "Disselboom" coins are the 1892½ pond and 5s coins. One has to be very careful, as there are forgeries of the "Disselboom" coins, especially the 5s. A genuine "Disselboom" 5s must have the wheels on the wagon the same size.
