The Strachan & Co token coins were minted in Europe as a solution to the problems faced by the Griqua Raad.
They were minted because of the absence of an alternative form of currency in the Nomansland area in which the Strachan and Company stores operated.
The coins were approved by the Griqua Government in 1874 as the region's currency.
There were four different types of token sets minted.
These were minted then put in general use as currency in the area of Nomansland (south of Natal) from about 1874 to 1932 when they were outlawed by (South African) Government decree and when currency and banks became more accessible (banks opened in Ixopo some 20 miles from Umzimkulu).
Over 20,000 coins were counted in 1980 when research on these tokens was first undertaken by Scott Balson. Since then several thousand more tokens have come to light - revealing an enormous volume of coins whose numbers (estimated between 50 to 100,000) go far beyond the requirement of use in their trading stores.
All Strachan and Co tokens were holed at 12 o clock so that the natives could wear the coins around their necks together with their beads. The sound that they made when they clinked together resulting in the native name of "kence" (pronounced "kenhjle").
The rarest set of S & Co is the Mountain Home set with the old 1/- "in goods" variety being the rarest individual coin.
In the 1980s the Strachan & Co stores were sold by the Strachan's to the South African government and the family left what was then known as the Transkei.
After Ken Strachan, the last in the family to run the stores, left Umzimkulu he took and stored the coins that were catalogued by Scott Balson before having them destroyed in the late 1980s. The new caches of hundreds of Strachan and Co coins appearing today reflect the sheer volume of these coins once in circulation and use as currency in Nomansland for over 50 years.
Despite the numbers of S&Co coins known to have survived (several thousand) their individual prices continue to climb.
From careful studying the new caches found we can say that there are only about 60 complete sets of the 16 Strachan and Co tokens in existence - making them highly valued and sought after today.
Complete sets of the 16 tokens change hands today for as much as US$3,000 (as at 2004).
