Invest in gold in UK tax free

A common way to invest in gold is to buy certain gold coins (not collectible). For instance: Maple Leafs in Canada, Kangaroos in Australia, but also Britannias in UK. Usually an investor has to pay capital gains tax on the money he is making when selling a product with profit. However, some coins from The Royal Mint are exempt from CGT (link here).

If you live in UK and can find good deals to buy Britannias, it makes sense to choose them instead of other gold coins (how to find good deals to buy gold coins).

Just as an example, here you can find a list of tax free coins from a UK dealer.
