| | The Royal Philatelic Society London - Revenue Stamps of South Africa 1902 - 1930 |
 | | The stamps to 4s were the smaller (or postage) size, while the stamps from 5s upwards were in the larger (or revenue) size. |
 | | However, since the revenue series was to only start at 6d, the plan was to have the 1d denomination as a dual purpose postage and revenue stamp. |
 | | Shortly before the Union stamps were to be issued on 1 September 1913, the Distributor of Stamps found that he was running short of the 3d, 6d and £1 denominations, and asked for, and received, permission from the Secretary of Finance to supply these denominations prior to the official issue date, if required. |
