Celebrate a historic milestone with The Sovereign 2025 Three‑Coin Gold Proof Set from The Royal Mint. This elegant trio features the 2025 editions of the Sovereign, Half Sovereign, and Quarter Sovereign - all struck in rose-gold alloy to proof standard, marking the final Rose Gold Sovereigns produced by the Mint.

The highlight of the set is the remastered Royal Arms reverse, originally designed by Jean-Baptiste Merlen in 1825, restored with modern precision. Each coin also displays the official obverse portrait of King Charles III by Martin Jennings, making this the first-ever trio to pair Merlen’s classic reverse with Charles III’s portrait.

As a limited release in a rose-gold alloy and the finale of this series, this set promises long-term appeal for collectors and investors alike.
