1 oz (31.10 g) gold coin Britannia, Great Britain (Mix year)

Gold Britannia 1oz coins have played a significant role in the precious metal bullion market since they were first released as assets for private investors in 1987. Nothing has changed and thanks to the Britannia's exquisite design, 24 karat purity and high liquidity continue to perform strongly as an investment tool. These coins are worthy of any investment portfolio regardless of year, although it should be noted that from 2013, the Royal Mint increased the gold purity to .9999 from 916.7 thus, later editions have a slight edge over earlier counterparts.
