The modern quarter sovereign, a smaller denomination of the sovereign coin, was Introduced in 2009 as part of the Royal Mint's sovereign series, the quarter sovereign has a gold content of 1.997g and a diameter of 13.5mm.

Its design features the profile of the monarch on the obverse and the St. George and the Dragon motif by Benedetto Pistrucci on the reverse. Variations exist in both the obverse and reverse (where cyphers are added) to commemorate special occasions.

This 'Box of Twenty' collection of quarter sovereigns is complete (save for one as there are actually 21 in total!), with each regular proof coin graded at PR70DCAM and the 2023 Matte Proof coin graded as PR70, showcasing the highest possible quality and condition of this complete collection.

The collection includes both the 2022 Jubilee Piedfort variation, a highly coveted piece with a mintage of only 70 and the 2023 Coronation Matte Proof, graded at PR70 (Matte). With only 25 of the 2023 Matte Proof coins minted and 23 held in private hands (the other two were respectively given to King Charles III and The Royal Mint Museum), the extraordinary rarity of this coin makes it the current central and key coin for the modern quarter sovereign collection.

I love, love, love these coins. In case it was not already obvious!
