South African Coinage · The Sterling Era
Union coinage.
The return of a nationally distinctive South African coinage after the ZAR period — struck in Pretoria under three monarchs, spanning the last full non-decimal era before the Republic. Visually cohesive, historically rich, and one of the most collected series in the country.
Obverse
Reverse
The three reigns
In Chronological OrderThe most structurally complex part of the Union series. Multiple early design phases — the 1923–24 sparrows farthing, the 1925 Threepence variety, the transition from beaded to non-beaded shillings, the introduction of the Protea sixpence in 1925. For type collectors, the richest chapter.
Three coinages — first (1937–1947), second (1948–1950), third (1951–1952). The wartime and post-war years. Strong silver denominations, the 1947 Royal Visit Crown, and the 1948 half-crown shown above. The gateway into serious Union collecting.
The closing chapter — the young Queen's portrait on the obverse, the familiar Union reverse system retained. Politically close to the Republic, visually continuous with the Union past. The last of the sterling structure before decimalisation in 1961.
George V design transitions
1923 – 1936The George V period covers three coinages across thirteen years, with multiple denomination-level design changes. A complete design-change set is materially harder than a date set — and far more representative of how the Union series actually evolved.
| Denomination | First (1923–1925) | Second (1925–1930) | Third (1931–1936) |
|---|---|---|---|
| Farthing (¼d) | Two sparrows · 1923–24 | — | — |
| Half Penny | Ship · 1923–26 | Ship · 1926–30 | Ship · 1931–36 |
| Penny | Ship · 1923–24 | Ship · 1926–30 | Ship · 1931–36 |
| Threepence | Mimosa wreath · 1923–25 | New design · 1925–30 | Continued · 1931–36 |
| Sixpence | Wreath · 1923–24 | Protea · 1925–30 | Protea · 1931–36 |
| Shilling | Hope, beaded circle · 1923–24 | Hope, no beaded circle · 1926–30 | Hope · 1931–36 |
| Florin (2/-) | Uncrowned shield · 1923–30 | Same | Same · 1931–36 |
| Half Crown (2/6) | Crowned shield · 1923–25 | Crowned shield · 1926–30 | Crowned shield · 1931–36 |
The key issue
George VI, 1947Landmark Commemorative
The 1947 Royal Visit Crown
Struck on the Oom Paul Press at the Pretoria Mint, the 1947 Crown bears the conjoined busts of King George VI and Queen Elizabeth — issued to mark the 1947 royal tour of South Africa. It remains one of the most widely recognised commemorative-style issues of the Union era, and a piece serious Union collectors prioritise early in the build. The visual weight, the historical moment, and the Pretoria provenance combine to make it the standout single coin of the George VI period.
Five routes in
For CollectorsThe most approachable route — one example of each principal design. Affordable enough to complete in mid-grades, instructive enough to teach the visual language of the entire series. The standard starting point.
Pick a single denomination — half crown, florin, shilling, sixpence — and complete every date from 1923 to 1960. Structured, finite, and deeply rewarding.
Materially harder than a type set. Includes every documented design transition — beaded vs unbeaded shillings, mimosa-wreath threepences, the early sparrows farthings. Far more representative of the full Union story.
Bronze and silver in premium mint state can become surprisingly scarce — particularly George V bronzes and original-surface George VI silver. The route for collectors who value preservation over completeness.
The 1925 Threepence, the 1923–24 farthings, the 1947 Royal Visit Crown, top-grade George VI silver. Build a smaller collection of standout pieces rather than a complete run.
