1 oz Cayman Marlin Gold Coin

The 1 oz Cayman Marlin Gold Coin

The Cayman Marlin is a legal tender bullion coin of the Cayman Islands, struck in .9999 fine gold by Scottsdale Mint of Arizona under agreement with the Cayman Islands Monetary Authority (CIMA). First issued in 2017 as part of what Scottsdale brands the "Cayman Sea Life" series, it features the blue marlin (Makaira nigricans), one of the most iconic game fish in the Caribbean and a genuine national symbol in a territory where sport fishing tournaments are major events. The arrangement gives the coin an unusual identity: sovereign-coin legal tender status from a Caribbean monetary authority, with production quality from a US private mint.

As a one troy ounce, four-nines gold coin, the Marlin competes directly with mainstream 1oz gold coins on metal content while differentiating on scarcity and theme. The series runs on limited annual mintages; even the higher-volume 1 oz silver version is capped at 50,000 coins per year, and the gold version is produced in lower numbers still. That puts it well below the unlimited-mintage sovereign programmes like the Maple Leaf, and closer in spirit to low-mintage collector-bullion hybrids.

Distribution is the practical consideration. The coin is available primarily through US-based dealers, with thinner coverage elsewhere, so price comparison matters more than for universally stocked coins. The buyer profile is someone who wants full investment-grade gold purity plus a distinctive Caribbean design and limited issue, and accepts that resale will route through a narrower dealer network than a Krugerrand or Eagle would.

Cayman Marlin Gold Coin Specifications

The reverse shows a blue marlin leaping from the water beneath the Cayman Islands coat of arms, which itself features a green turtle, a pineapple, and three stars on a shield with a rope border and the motto "He hath founded it upon the seas". That means the coin actually carries two marine creatures: the turtle in the arms and the marlin as the central motif. Inscriptions include "MARLIN" with weight and purity marks inside a decorative border. The obverse carried Ian Rank-Broadley's portrait of Queen Elizabeth II from 2017 to 2022, replaced by King Charles III from 2023. The coin's face value is denominated in Cayman Islands Dollars, a currency pegged to the US Dollar at roughly KYD 1 = USD 1.20, one of the strongest nominal currency values in the world; sources do not consistently document the gold coin's exact face value. Security relies on the reeded edge and fine line work in the wave patterns and marlin scales rather than micro-engraving or holograms.

Cayman Marlin Gold Tax Treatment by Country

At .9999 purity the gold Marlin clears the investment-gold threshold everywhere that has one, so purchase tax is rarely a factor.

• Cayman Islands: No income tax, no capital gains tax, no sales tax. Buying locally carries no tax implications at all.
• US: The primary market. No federal sales tax, and most states exempt bullion; a minority still tax it or apply purchase thresholds. Gains are taxed at the collectibles rate of up to 28% on long-term holdings.
• UK: 0% VAT as investment gold. Not CGT-exempt, since it is not UK legal tender; gains above the £3,000 annual allowance are taxable, which separates it from a Britannia.
• Canada: Gold refined to 99.5% or higher purity in coin form is exempt from GST/HST, which the .9999 Marlin satisfies.
• Australia: GST-free as investment-grade gold at 99.5%+ purity; CGT applies with a 50% discount after 12 months.
• EU: Investment gold coins (post-1800, legal tender, at least 900 fineness) are VAT-exempt under the EU directive.
• Hong Kong and Singapore: No sales tax on investment-grade gold and no capital gains tax in either jurisdiction.

Cayman Marlin vs Trident, Eastern Caribbean Coins, and Sovereign Bullion

The Marlin's nearest relatives are its stablemates. Scottsdale Mint has built a portfolio of Caribbean legal tender programmes, the Barbados Trident, the Cayman Marlin, and the Eastern Caribbean States coins, giving the Arizona mint a near-monopoly on Caribbean bullion production. Against the Barbados Trident, the Marlin is the scarcer issue: the silver Trident's mintages have ranged from 100,000 up to 1,000,000 depending on year, while the silver Marlin is capped at 50,000 and the gold runs lower still. Both share the same producer and the same sovereign-authorised, privately-struck model.

Against mainstream sovereign coins, the comparison is purity-equal but liquidity-unequal. At .9999 fine, the gold Marlin matches the Maple Leaf, Britannia, and Kangaroo, and exceeds the 22-carat Krugerrand and Eagle in fineness, though every 1 oz coin in that group contains the same full ounce of fine gold. What the big sovereign programmes offer is distribution: they are stocked by effectively every dealer worldwide and carry the tightest buyback spreads, while the Marlin trades mainly through US dealers. A buyer optimising purely for cost and exit takes the mainstream coin; the Marlin's case rests on its limited mintage, Caribbean theme, and relative novelty within a 1oz gold coin portfolio. The 1 oz silver Marlin, with its CI $1 face value and 38.6 mm flan, offers the same design at a far lower entry price for buyers drawn to the series rather than the metal.
