1 oz Cayman Marlin Gold Round

Caribbean Legal Tender from Scottsdale Mint

The 1 oz Scottsdale Mint Cayman Marlin Gold Round is legal tender of the Cayman Islands, struck in .9999 fine gold by Scottsdale Mint (Arizona, USA) under agreement with the Cayman Islands Monetary Authority (CIMA). The series features a blue marlin leaping from the ocean, referencing the Cayman Islands' reputation as a world-class sport fishing destination in the Caribbean.

First issued in 2017 as part of the broader Cayman Sea Life coin programme, the gold Marlin carries sovereign-coin status despite originating from a US private mint. This distinction matters for tax and IRA purposes: the coin has a face value in Cayman Islands Dollars and is authorised by a recognised monetary authority, giving it legal protections that generic private mint rounds lack.

The silver version has an annual mintage limited to 50,000 coins, and the gold version is produced in lower quantities. Scottsdale Mint has built a portfolio of Caribbean legal tender coin programmes (including the Barbados Trident and Eastern Caribbean States coins), giving them production experience at sovereign-coin-grade quality while maintaining pricing below the major government mints. For buyers seeking a recognised legal tender gold coin at premiums below mainstream sovereign products, the Cayman Marlin occupies a practical niche between private rounds and government coins from the US, Canadian, or British mints.

Cayman Marlin Gold Coin Specifications

The obverse featured Queen Elizabeth II (Ian Rank-Broadley portrait) from 2017 to 2022, surrounded by calm ocean water patterns with inscriptions including "ELIZABETH II," "CAYMAN ISLANDS," the denomination, and year. From 2023 onward, the obverse carries the portrait of King Charles III. The reverse depicts a blue marlin (Makaira nigricans) in mid-leap with the Cayman Islands coat of arms (featuring a green turtle, pineapple, and three stars on a shield with a rope border and the motto "He hath founded it upon the seas") positioned at the top, alongside weight and purity markings.

The reeded edge provides basic authentication through feel and visual inspection. Detailed fine-line work in the wave patterns and marlin scales adds engraving complexity that is difficult to replicate in counterfeits. Individual coins ship in protective plastic capsules, with sheets of 5 and boxes of 125 (25 sheets) available for larger orders. The coin shares its 38.6mm diameter with several other 1 oz silver coins in the market.

Cayman Marlin Tax Treatment

As legal tender issued by a recognised monetary authority, the Cayman Marlin gold coin qualifies for investment gold treatment in most jurisdictions. The Cayman Islands themselves impose no income tax, no capital gains tax, and no sales tax, making local purchase entirely tax-free.

• United States: The .9999 gold purity qualifies for IRA inclusion under IRS Section 408(m). The legal tender status from a recognised government authority strengthens IRA eligibility compared to private rounds without face values, as custodians generally prefer sovereign-issued coins. Sales tax treatment follows state-level bullion exemptions; approximately 35 states exempt investment gold entirely. Capital gains taxed at the 28% collectibles rate for holdings over one year.
• United Kingdom: VAT-exempt as investment gold. A legal tender coin above .900 fineness from a recognised issuing authority qualifies under retained EU investment gold rules. Not CGT-exempt (not UK legal tender). UK CGT applies at the individual's marginal rate with the £3,000 annual allowance.
• EU: VAT-exempt as investment gold under Directive 98/80/EC. Legal tender coin of .999+ fineness from a recognised monetary authority qualifies across all member states.
• Canada: GST/HST exempt as gold exceeding 99.5% purity in coin form.
• Australia: GST-free as investment-grade gold at 99.5%+ purity.
• Singapore: GST-exempt under IPM provisions for qualifying gold coins from recognised issuing authorities.

The Cayman Islands Dollar is pegged to the US Dollar at approximately 1 KYD = 1.20 USD, making it one of the strongest currencies by nominal value globally.

Cayman Marlin vs Other 1 oz Gold Coins

The Cayman Marlin competes in a middle ground between premium sovereign coins and generic private mint rounds. Its legal tender status from CIMA gives it institutional legitimacy that pure rounds lack, but it does not carry the global recognition or dealer network of major sovereign mint products.

Against the 1 oz American Gold Eagle or 1 oz Canadian Maple Leaf, the Marlin trades at lower premiums but with significantly narrower resale liquidity. Major sovereign coins are universally recognised and accepted by every bullion dealer worldwide. The Cayman Marlin is primarily distributed through US-based dealers and may not be immediately recognised by dealers in other markets, particularly outside North America.

Against Scottsdale Mint's own Barbados Trident gold coin, both share the same producer and Caribbean legal tender concept. The Trident has broader distribution and higher mintage numbers in silver (100,000 to 1,000,000 depending on year versus the Marlin's fixed 50,000), giving it slightly better recognition among US dealers. Both use .9999 gold for their gold versions.

The 50,000 annual mintage (silver) positions the Marlin well below semi-numismatic territory but also well below the millions produced by sovereign mints annually. For buyers who value a legal tender coin with limited production at lower premiums than mainstream options, and who plan to sell through major US online dealers rather than local coin shops, the Marlin represents a practical middle path between the extremes of generic rounds and premium sovereign coins.
