The Orange Free State
began to issue postage stamps in 1868, and continued until 1897.
The O.F.S. was formally annexed to the British Crown and renamed the Orange River Colony on the 28th of May 1900.
The sole design used was an orange tree, with the inscription "Oranje Vrij Staat" in the margin. The stamps were typographed
by De La Rue and Company
, and came in denominations from one penny to five shillings, in various colours. Periodic shortages forced the use of overprints
, in 1877, 1881, 1882, 1888, 1890, 1892, 1896, and 1897. The stamps of the republic are generally common today, but some of the overprints are scarce. Many kinds of overprint errors are known (inverted, double, etc), and some of them command high prices.
A variety of revenue stamps
were issued both as the Orange Free State and the Orange River Colony.
