1/2 oz Pobjoy Mint Noble Platinum Coin

The 1/2 oz Isle of Man Platinum Noble

The Noble holds a position no other coin can claim: it was the world's first platinum bullion coin struck for investors, first minted in November 1983 by the Pobjoy Mint for the Isle of Man Government, a Crown Dependency of the British Crown. Every platinum investment coin that followed, from the Canadian Maple Leaf to the American Eagle, walked through the door the Noble opened. The 1/2 oz coin contains 15.55 grams of .9995 fine platinum, the purity all major platinum coins later standardised on.

The series is as scarce as its claim is large. Platinum Noble production ran only six years, from 1983 to 1989, and the wider series was minted irregularly rather than annually, with no regular production since 2018. Three different private mints struck Nobles over the decades: Pobjoy Mint from 1983 to 2016, Coin Investment Trust in 2017, and Tower Mint in 2018. Surviving platinum examples are genuinely scarce compared with continuously minted competitors, which moves the coin toward collector territory rather than pure bullion.

The Noble is Isle of Man legal tender, but with an unusual twist borrowed from the Krugerrand model: it has no fixed face value, instead being legal tender to the value of its metal content, with the denomination stamped simply as a fraction of "ONE NOBLE". For a buyer comparing it against modern platinum coins, the choice is between the pioneer with historical cachet and limited supply, and current-production coins with deeper liquidity.

Platinum Noble Denominations and Dimensions

The 1/2 oz coin sits in a five-denomination bullion range, all struck in .9995 fine platinum.

The obverse carries a portrait of Queen Elizabeth II, with four different versions used across the decades of production. The reverse shows a Viking longship with four birds and the Isle of Man triskelion, the island's three-legged coat of arms, inside an elaborate Viking knotwork border reflecting the island's Norse heritage. Rare 5 oz and 10 oz proof platinum Nobles also exist, with mintages of just 26 and 15 pieces. The series later expanded into gold (.9999, from 1994), silver (.999), and a single one-ounce palladium issue in 2012. A 1996 issue claimed the title of the world's first holographic coin, with a holographic sail on the Viking ship.

Tax Treatment of the Platinum Noble

Platinum never enjoys gold's tax exemptions in Europe, and the Noble's Isle of Man status adds a wrinkle for UK buyers.

• UK: 20% VAT on platinum. The Isle of Man is not part of the UK, so the Noble is not Royal Mint legal tender and is not automatically CGT-exempt; gains may be subject to UK CGT, unlike a Platinum Britannia. Anyone relying on a CGT exemption for an Isle of Man coin should verify it with a tax adviser.
• US: no federal sales tax, most states exempt bullion, and the .9995 purity meets the 99.95% IRA requirement for platinum. Long-term gains are taxed at the collectibles rate of up to 28%.
• EU: full national VAT applies to platinum, as there is no investment platinum exemption equivalent to the gold one.
• Canada: GST/HST exempt at 99.5%+ platinum purity.
• Australia and New Zealand: GST-free as investment-grade platinum.
• Singapore and Hong Kong: Singapore exempts qualifying legal tender platinum coins from GST; Hong Kong has no sales tax. Neither taxes capital gains.
• Isle of Man: the island itself has no capital gains tax.

The Coin That Made Platinum an Investment Metal

Before 1983, no sovereign or semi-sovereign entity had struck platinum specifically for investors. The metal traded industrially, but there was no platinum equivalent of the Krugerrand. The Isle of Man Government and the Pobjoy Mint changed that in November 1983 with the platinum Noble, named after the medieval Noble, a fourteenth-century English gold coin. The Canadian Platinum Maple Leaf followed five years later in 1988, the Australian Platinum Koala the same year, and the American Platinum Eagle not until 1997, fourteen years after the Noble led the way.

Production was never conventional. The platinum bullion run lasted just six years, through 1989, with the 1985 issue the most common date at a mintage of 99,000. Gold and silver Nobles appeared from 1994 and continued sporadically until 2018, by which point the series had passed through three minting houses. Along the way it collected a string of firsts and oddities: the claimed first holographic coin in 1996, bimetallic editions pairing gold with platinum in 1995 and silver with gold in 2009, and the 2012 palladium one-ounce, the only palladium issue in the series.

Nothing has been struck since 2018 and the series appears dormant. That dormancy is now part of the appeal: the Noble's importance is historical, as the catalyst for platinum becoming an investment-grade metal, and its scarcity is real rather than manufactured, the by-product of a short production window four decades ago.

Noble vs Platinum Eagle, Maple Leaf, and Britannia

Every modern rival matches the Noble's .9995 purity, so the comparison is about availability and market depth rather than metal. The 1/2 oz American Platinum Eagle has US government backing, ongoing production, and the strongest resale demand in the American market; the Canadian Platinum Maple Leaf offers Royal Canadian Mint pedigree, though its production has been intermittent. Both are continuously distributed in a way the Noble, out of production since 2018, simply is not. The Noble's counterweight is scarcity and the pioneer story, which give it collector appeal the open-mintage coins lack.

For UK buyers the Platinum Britannia changes the calculation entirely. All platinum coins carry 20% UK VAT, but the Britannia is UK legal tender and therefore CGT-exempt on sale, while the Noble's Isle of Man status leaves its UK CGT treatment uncertain. From a pure tax standpoint the Britannia is the only platinum coin with a clear UK advantage.

Practical platinum considerations apply to all of them. The platinum coin market is small: fewer dealers stock it, spreads are wider than gold, and fractional sizes like this 1/2 oz carry higher percentage premiums than 1 oz coins because production runs are small and demand inconsistent. A fractional coin from a dormant series compounds both effects: harder to find, and a thinner buyer pool when selling. The Noble is best understood as a piece of platinum history with bullion value attached, not the cheapest route into the metal; that route runs through current 1 oz coins or platinum bars.
