The British colony of Zululand issued revenue stamps in 1888. The only set consisted of seven values of 1d, 1s, 5s, 9s, £1 (two different colours), £5 and £20 of Natal revenues overprinted ZULULAND in a similar overprint to that used for postage stamps. The 1d later became valid for postal use as well. All the higher values now command high prices and are quite rare. In addition to this issue, the same Natal £5 is known with a different overprint in violet, but it is not known if this was a legitimate issue or not.
