About this coin
2018 Gold Proof Quarter Sovereign – Sapphire Anniversary Privy Mark
This 2018 Gold Proof Quarter Sovereign carries a special crown-and-"65" privy mark, struck to mark the Sapphire Anniversary of Queen Elizabeth II's Coronation — 65 years since she was crowned at Westminster Abbey on 2 June 1953. The privy mark appears to the left of the date on the reverse, with Benedetto Pistrucci's "B.P." initials positioned to the right of his iconic Saint George and the Dragon design.
Graded NGC PF70 Ultra Cameo — the maximum attainable grade, indicating a flawless strike with no imperfections under magnification and strong cameo contrast between the frosted devices and mirrored fields. Only 53 examples have been certified at this grade, making it one of the more difficult Sapphire Anniversary privy mark coins to source in top condition.

Why This Coin Stands Out
Individually issued proof Quarter Sovereigns are already scarce compared to their full Sovereign counterparts, and privy-marked years like 2018 add an extra layer of desirability. A PF70 Ultra Cameo certification means this example represents the technical ceiling of the issue — there is no higher grade NGC can award. For collectors building a Sapphire Anniversary set or a top-graded Quarter Sovereign run, this is a genuinely difficult coin to replace once sold.
As UK legal tender gold, this coin is exempt from Capital Gains Tax for UK residents and free from VAT under current investment gold rules.

Can I verify the coin's grade?
Yes. Every NGC-certified coin has a unique certification number visible on the slab label. You can verify the grade, coin details and population data at NGCcoin.uk using the cert number shown.
What is the population or top pop figure?
The NGC census records how many examples of each coin have been graded at each level. A Top Pop coin means no other example has achieved a higher grade — making it the finest certified specimen in existence for that issue.
Do you offer part exchange?
Yes. We accept all proof coins and graded coins in part exchange, including NGC and PCGS certified coins, boxed gold and silver proofs, and proof sets.
