Certified Gold Proof Coins
Explore our range of certified gold Proof coins, independently authenticated and professionally graded by leading third-party grading services including NGC and PCGS.
Proof coins are specially produced collector coins, typically struck using carefully prepared dies and planchets to create a high-quality finish. Our certified collection includes selected British gold Proof coins across different years, denominations and designs, including high-grade examples such as PF70 Ultra Cameo and PR70 Deep Cameo.
NGC and PCGS Graded Proof Coins
Professional certification provides independent authentication and an assessment of a coin's condition. NGC and PCGS encapsulate certified Proof coins in protective holders displaying information including the coin's identity, grade and relevant designations.
NGC generally uses the PF designation for Proof coins, while PCGS uses PR. Grades such as PF70 Ultra Cameo and PR70 Deep Cameo represent the highest numerical grade within their respective grading systems. Learn more in our PCGS vs NGC guide, our guide to PF70 Ultra Cameo and our comparison of PF69 vs PF70.
Proof Coin Mintage and Certified Population
When researching a certified Proof coin, it is important to distinguish between Maximum Coin Mintage, Limited Edition Presentation and certified population. These figures measure different aspects of a coin's original issue and subsequent certification.
Population figures can change as additional coins are submitted for grading. Our individual product pages therefore state grading populations at the time of checking where appropriate. Learn more in our guides to coin population reports and coin population vs mintage.
