Buy gold Guineas at BullionByPost. We sell a wide range of Guineas, and at 22 carat purity they are very valuable gold coins. These quarter ounce gold coins are considered a rarity and carry a sizeable collectors value due to their age, having been produced between 1663 and 1814.
Many monarchs featured on Guineas over the years, including Charles II, James II, Mary II & William of Orange, William III of Orange on his own after Mary’s death, Queen Anne, George I, George II, and finally George III. After 151 years the Guinea was phased out in favour of gold Sovereigns and a new Pound coin, both of which we still use 204 years later.
The Guinea is a British gold bullion coin that was minted for several centuries before being replaced by the pound. It weighs roughly one quarter of a troy ounce and is made from 22 carat gold. This makes it very similar to the gold Sovereigns produced by the Royal Mint.
The name 'Guinea' comes from West Africa, where the gold was sourced during British colonialism to produce these coins. The Gold Coast (now modern day Ghana), as well as neighbouring nations Togo and Guinea itself, were all sources of gold for the production of these coins.
The size of the coins varies quite a lot per coin, despite the fact that guineas were the first machine-struck coin. Some guineas are as small as 16mm in diameter, while other later ones are around 24 to 25mm. The official valuation of the time varied too, but generally a guinea was worth 21 shillings (1717 to 1816).
