How to Identify the South Africa Farthing

Start with the obverse portrait and legend. A South Africa Farthing shows a royal head ringed by an abbreviated Latin legend; if it includes REX IND IMP you have a King's issue struck before 1947, and a left-facing head with George VI's name places it in the 1936-1952 reign, as on the 1939 coin here. A queen's portrait and legend instead indicate a later Elizabeth II farthing.

Turn to the reverse to separate the coin from the British farthing. The Union piece carries a small South African bird design, not the seated Britannia used in Britain, and the country name appears in both English and Afrikaans. That bilingual naming is a reliable tell: British and most other Commonwealth farthings are English-only.

Use size and metal as a cross-check. The farthing is bronze, small at roughly 20 mm across, and clearly the tiniest of the Union's three bronze coins; the halfpenny and penny are visibly larger. A genuine coin is non-magnetic and light in the hand, and a browning or red-brown bronze surface is normal. A silvery or magnetic coin of this size is not a farthing.

Read the date and country name carefully, since the series spans multiple reigns and both George V and George VI Kings' issues share the REX IND IMP style. The date fixes the year and reign, and the mint was Pretoria; there is no separate mint-mark letter to hunt for. Note that some years are scarcer than the common run, so the date matters for value.

Be alert to look-alikes and condition traps. Do not confuse the Union farthing with British, Australian, or other Commonwealth farthings of the same era, which name their own country and lack the Afrikaans legend. On a small bronze coin, harsh cleaning, corrosion, and artificial toning are the main hazards; for any coin claimed as a scarce date or high grade, get authentication from a reputable dealer or grading service before relying on it.
