For a coin of this calibre, silence in the marketplace speaks volumes. Since its release by the Royal Mint in 2017 at £14,490, not seen single complete gold proof set that has surfaced publicly — a remarkable testament to both its extreme rarity and the discernment of those privileged enough to acquire one.
With just 25 sets issued worldwide, these coins have been quietly absorbed into long-term collections, remaining untouched for nearly a decade. Now, for the first time, we have secured an example from a long-standing client who has chosen to realise his gains — having seen his investment grow from just under £15,000 to £45,000 in nine years.
This set is now available at £47,500, offering a rare opportunity to acquire a piece that almost never returns to the open market.

What truly defines this set is not simply its gold content — though with approximately 7 ounces of 24ct gold it carries a strong intrinsic foundation — but its position within the hierarchy of rarity.
Coins with comparable mintages, given time, sit comfortably in the £200,000 to £500,000 range and beyond. This is not a short-term trade or
What truly defines this set is not simply its gold content — though with approximately 7 ounces of 24ct gold it carries a strong intrinsic foundation — but its position within the hierarchy of rarity.
Coins with comparable mintages, given time, sit comfortably in the £200,000 to £500,000 range and beyond. This is not a short-term trade or speculative purchase; it is a medium to long-term hold, a generational asset to be passed down, admired, and ultimately realised at a far higher level.
Opportunities such as this are exceptionally rare — not because they are heavily marketed, but because they are usually never available at all.

If you understand what true rarity means — not marketing scarcity, but genuine global limitation — then this is a moment to act with conviction. Opportunities like this do not linger, nor do they repeat. We are offering this set to a discerning collector or investor who recognises both its significance and its future potential.

Advancement through Adversity
As weary soldiers fought lengthy battles across devastated ground, 1917 called for selfless heroes, medical progress, technological advancement and a new form of art to help the public comprehend the reality of a relentless modern war. The innovation demanded by a newly industrialised war is explored in The Royal Mint’s First World War Six-Coin Set for 2017, with six new coins continuing our journey from Outbreak to Armistice.
By the fourth year of the First World War, both sides were deadlocked in trench warfare. Advancement in areas from medicine to machinery proved vital in ending the conflict the following year, while many of the innovations during this time, such as blood banks and plastic surgery, benefit public healthcare to this day.
This is the fourth six-coin set in the series, with each intricate coin design and emotive inscription paying tribute to their subjects. The accompanying booklet reveals the story that inspired each coin including the bravery of Captain Noel Godfrey Chavasse VC, the dedication of the medical services and the cultural importance of the war artist. The Sopwith Camel, the newly engineered plane that claimed the skies, is joined by a haunting depiction of the horror of gas warfare and a final design.

Limited to only 25 gold sets worldwide, this collection is a true modern numismatic masterpiece, bridging powerful history and exceptional artistry
The six designs reflect key aspects of 1917 — a year marked by tragedy and breakthroughs, endurance and innovation
In the world of high-end numismatics, rarity isn't just a number — it’s the foundation of value. When only a handful of collectors can own a coin, scarcity drives desirability, prestige, and price.
The 2017 Royal Mint WWI Gold Proof Six-Coin Sets — each limited to just 25 sets worldwide — rank among the rarest modern gold issues ever produced by a major mint. To put that into context:
