A unique pair of 1886 Proof Sovereign and Proof Half Sovereign, brilliant FDC, the two coins offered for $280,000.
The Melbourne Mint struck a Proof Sovereign and a Proof Half Sovereign in 1894, using dies prepared by the Royal Mint London. The coins left the mint, as a pair, more than a century ago destined for the collection of revered British collector, John G. Murdoch.
They are back in their country of origin, the two coins presented today as the mint intended. As a pair. Naturally heirloom-worthy, the pair offers rarity you can’t replicate. Together, they are unique.
Brilliantly preserved, the pair is offered for $150,000.
We have sold a handful of individual proof sovereigns out of this era. And even less proof half sovereigns. It is the second only Melbourne Mint gold proof pair we have offered in fifty-four years of trading. And that’s a powerful statement given that this is an area of the rare coin market that is our strength.
Australia’s Proof Sovereigns and Proof Half Sovereigns are coins that were quite literally, fit for royalty. They are powerfully irresistible. And they are respected for the history they represent. They are sought after, the world over, for their exclusivity.
You don't buy a piece of proof gold and then put it aside. You savour the moment and you take in its glory, and you show it around to family and friends for they are exclusive and they are beautiful.
Today's collectors are showing a marked preference for pairs if, and when, they are available. So not one coin, but two, the Proof Sovereign and the Proof Half Sovereign together. The current sentiment is that a pair is the mint's complete story, the total narrative.
And this principle is being consistently taken up and reflected in Coinworks sales. The 1901 Perth Mint Proofs sold as a pair for $525,000, the purchaser commenting that he would not have bought an individual coin because it was not the complete story. The same views were expressed by the purchaser of the 1871 Sydney Mint Proof Sovereign and Half Sovereign. And in March 2026, a Proof 1896 Sovereign was acquired by a collector that already held the 1896 Proof Half Sovereign.
The pursuit of completion is also being shown in other areas of the market. The Complete Kookaburra Collection sold within a few hours of its release, the key here is that it was complete. A date set of kookaburra pennies, complete for each of the dates in which the coins were struck, is also today a strong collector favourite. In February 2026, a Coinworks client completed a 'mint' set of Holey Dollars: four Holey Dollars representing the mints Madrid, Lima, Potosi and Mexico.
Complete sets are naturally heirloom-worthy. They’re easier to pass down, easier to explain, and more likely to retain their identity over generations. Families understand the concept of the full set instantly.
Let's also be clear. There is a significant amount of collector/investment dollars available globally. And buyers with significant financial resources are looking to spend their money on an item that has substance. And pairs or sets have more substance than an individual coin.
Coinworks is also making this offer to clients who are considering a pair of proofs. Take the first coin and we will guarantee to hold the second coin, and hold the price, for six months to facilitate a purchase of the pair.

The Young Head portrait appeared on Australia’s sovereigns for seventeen years, between 1871 and 1887. Both the Sydney Mint and the Melbourne Mint were prolific producers of circulating coinage during this era. Both mints were however miserly producers of proof coinage.
Sydney Mint proof sovereigns in the Young Head era have been sighted in four years, 1871 (this coin), 1879, 1880, and 1883. And of the Melbourne Mint, in only two years, 1885 and 1886. Coins of Record were struck in 1874 and 1875 at the Melbourne Mint, to specimen quality.
This 1886 Proof Half Sovereign is the only known example and was also originally owned by John G Murdoch and ex Nobleman, Spink Auctions 1985, Philip Spalding
From a business that began manufacturing musical boxes, J. G. Murdoch’s company became a leader in the music industry, manufacturing pianos and organs. His successes provided him with the financial means of securing coins of the highest rarity and quality.
Two examples of the Melbourne Mint Proof 1894 Half Sovereign were held in the Murdoch Collection acquired direct from the Melbourne Mint. Both coins were offered at auction in 1903 by Sotheby, Wilkinson & Hodge, this example noted as Lot 637.
The coin re-surfaced and was offered at an Australian auction house, Noble Numismatics, in April 1998, as Lot 1563. Coinworks acquired this coin by private treaty from Barrie Winsor in 1999.
A second example of the 1894 Proof Half Sovereign is known and has appeared at an Australian auction. (The assumption that it was also part of the Murdoch Collection as he was the prime holder of Australia's Veiled Head proof coinage in the early 1900s.)
Australia's Gold Proof Coinage
When the Royal Mint London or the British Museum requested a sovereign or half sovereign from an Australian Mint, they were never sent a circulation strike. Nor would a circulation strike be presented to the monarch, gifted to a dignitary or sent to an influential collector. And a circulation strike would not be displayed at a Colonial Exhibition.
An individually crafted presentation piece would be specially created for the occasion, minted to a proof or specimen finish. The technical term for such a piece is 'Coin of Record'.
A Coin of Record is an artistic interpretation of coinage, a strikingly beautiful coin beyond ordinary currency. Individually crafted to standards far exceeding that required of a circulating coin, using special coining techniques. Whereas production of circulating coinage was dictated by Government, Coins of Record were struck at the discretion of the mint master.
Coins of Record were not produced every year and, as they were individually crafted, the process was time consuming and the mintages minuscule. For gold proofs, generally ten pieces or less. There were several occasions when only a single coin was struck.
Coins of Record of Australia's sovereigns and half sovereigns are visually stunning, distinguished by brilliant golden-mirror surfaces. And it is their beauty and their ultra-exclusivity that drives demand.
Australian gold proof coins moved onto the international stage when the collection of John G. Murdoch was liquidated via Sotheby, Wilkinson & Hodge in London in 1903, following his passing in 1902. Murdoch held an extensive collection of gold proofs, including coins from the Sydney Mint, Young Head, Veiled Head and Jubilee eras.
The reputation of Australia's gold proof sovereigns and half sovereigns as an international commodity was set in stone in 1903, a widespread regard that holds to this very day, right across the globe. Recent international auction results (February 2026) confirm the status of Australia's gold proof coins as a globally traded commodity. It is noted that the frosted proofs of the Melbourne Mint (such as the 1894s) are keenly sought by American collectors.
