A record number of investors sold gold coins to the Royal Mint between April and June for tax-free gains, as the price of gold reached all-time highs.

The value of gold coins resold to the Royal Mint reached an all-time high, with a 75% increase quarter-on-quarter and 55% year-on-year.

The Royal Mint operates a buyback program where customers can sell their gold coins.

In one case, an investor purchased gold coins from the Royal Mint in October 2024, when the gold price was £1,972.40, and sold them in June 2025 for a capital gains tax-free profit of £70,000, when the gold price had risen to £2,447.74.

Driving the increase in investors reselling the precious metal was the gold price, which set five new all-time highs in sterling, reaching a peak of £2,611.66 in April.

This led to “unprecedented engagement from British investors,” according to The Royal Mint.

There was also record demand because Royal Mint bullion and coins are exempt from capital gains tax, as they are classified as legal tender. Gold bullion and coins purchased outside the Royal Mint are not exempt from capital gains tax.
