2009 Royal Arms Shield One Pound Gold Proof Coin

22-carat gold proof 2009 Royal Arms One Pound coin from The Royal Mint in the original presentation case with a numbered COA.

The Shield of Royal Arms design was introduced to UK currency in 2008, replacing Eric Sewell's Coat of Arms design. Matthew Dent's reverse complements the new definitive designs, introduced across British coinage, which together form a shield of arms.

• The obverse displays Ian Rank-Broadley's definitive coinage portrait of Queen Elizabeth II
• The edge reads 'DECUS ET TUTATMEN', which means 'An Ornament and a Safeguard'
• Just 540 of these 916.7 gold proof coins were struck in 2009, making these a low-mintage issue
