The mighty oak. 2018 silver proof 10p coin.

The 2018 Letter O Oak Tree Silver Proof 10p serves as a stunning tribute to nature and endurance within The Royal Mint's acclaimed Great British Coin Hunt. While its base-metal counterpart rarely surfaces in pocket change, this collectors' edition transitions a humble tenpence piece into a premium numismatic asset. Struck in 6.50 grams of .925 sterling silver, the coin holds 6.01 grams of pure silver content. Its flawless, mirror-like proof finish contrasts beautifully with the frosted elements of the engraving, ensuring a high-appeal addition to any silver stack.

The reverse design captures a quintessential symbol of the British landscape, featuring an elegant oak branch with three detailed leaves and a single acorn twined around a prominent letter ‘O’. As the national tree of England and Wales, the mighty oak represents strength, history, and deep-rooted protection across the United Kingdom. Flip the coin over to the obverse, and the pristine silver surface provides a striking canvas for Jody Clark’s definitive fifth portrait of Queen Elizabeth II, cementing its status as an important slice of modern sovereign history.

From an investment standpoint, this piece offers a combination of immense scarcity and excellent liquidity on secondary platforms like eBay. It features an exceptionally low maximum issue limit of 15,000 pieces, making it vastly scarcer than standard circulating currency. Crucially for British precious metal stackers, because it holds legal tender status, it benefits from a highly advantageous tax classification—meaning any future profits generated from its sale are completely exempt from Capital Gains Tax (CGT).
