Royal Observatory, Greenwich £2 (2025)

The Royal Observatory £2 was never struck for circulation, so the market consists of brilliant uncirculated coins from the 2025 annual set, Royal Mint packs, capsules and certified cards, plus proofs. It was also sold in limited-edition coin covers in brilliant uncirculated, silver proof and gold proof, and each of those is valued as its own item. On a loose coin, check the fine clock numerals and the star chart lines for scratches. A sealed Royal Mint pack sells ahead of a loose coin.

The Royal Observatory, Greenwich £2 was not issued for circulation, so it has no rarity rank.

The Royal Observatory £2 has a small globe on a stand in the foreground, marked W and E, with a large clock face of Roman numerals behind it. The lines of a star chart cross the upper left of the centre. THE ROYAL OBSERVATORY · GREENWICH · runs around the top of the yellow ring, with the founding year at the lower left and 2025 at the lower right. The edge reads PERFECTING THE ART OF NAVIGATION, and the obverse shows King Charles III.

King Charles II founded the Royal Observatory at Greenwich by Royal Warrant, making it the first state-funded, purpose-built scientific institution in Britain. Its task was practical: better navigation at sea, more accurate maps and reliable timekeeping. Over the centuries it helped solve the problem of finding longitude, gave the country a standard time, and became home to the Prime Meridian, the line of zero longitude that divides the eastern and western hemispheres. For the 350th anniversary in 2025, Henry Gray, who designed the George Orwell £2 the same year, brought several of the observatory's tools and discoveries together in one picture. A globe on a pedestal, marked W and E on either side of the meridian, stands in front of a clock dial with Roman numerals modelled on the Shepherd Gate Clock, one of the first public displays of Greenwich Mean Time. Across the upper left run the lines of a star chart showing Ursa Minor and its brightest star, Polaris. THE ROYAL OBSERVATORY · GREENWICH · runs around the top of the ring. The edge inscription, PERFECTING THE ART OF NAVIGATION, is taken from the founding Royal Warrant. The coin appeared first in the 2025 annual set.
