One hundred pounds

There was a time when one hundred pounds was a considerable sum of money. Taking inflation into account, £100 in 1924 would be the equivalent of £7,619 today, a huge devaluation following 100 years of inflation for the pound sterling.

One hundred pound coin

There has been talk of introducing a one hundred pound coin for years but, so far, the Bank of England has refused to do this for common circulation currency that we use every day. The declining use of cash in society means it is highly unlikely this would ever come to pass.

There are 'legal tender' £100 coins, but these are commemorative or bullion coins only, and are not considered circulating currency. In the UK, a one hundred pound coin will likely be made of gold, silver or platinum. They have a £100 face value but are, in reality, worth far more on account of their precious metal content. Coin collectors – or numismatists – may even pay an additional premium for specific examples. This means you would be ill-advised to try spending them in your local high street shop!

Precious metals in the form of bullion and commemorative coins offer tax advantages over bars of the same weight. A one hundred pound coin made of gold, silver or platinum will benefit from being exempt of CGT, as the face value of £100 classes them as legal tender. Gold bars and coins, unlike other precious metals, are also VAT-free. This makes £100 precious metal coins attractive to both investors and coin collectors alike.

£100 silver coins

Issued for the first time in 2015 (and sold at its face value) was the Big Ben silver £100 coin. It was designed by Glyn Davies and Laura Clancy. Only 50,000 were minted from .999 fine silver and all sold within just 11 days.

The Big Ben coin was quickly followed by the Buckingham Palace £100 coin, and Trafalgar Square £100 coin in 2016. These are now already changing hands for well over their face value.

£100 gold coins

There are many gold commemorative and bullion coins with a face value of £100. These include the gold Queen's Beasts series, gold Lunar New Year series and gold Royal Arms coins. The most popular, and best known £100 gold coin is the gold Britannia.

Gold Britannia

The gold Britannia was first minted in 1987 from 22 carat or 916.7 fineness gold. After 2013, it was minted from 24 carat or 999.9 fineness. All contain one ounce of pure gold, and were classed as one hundred pound coins.

Depending on prices in the gold commodities market, Britannia coins can currently trade for around £1,600. Numismatic interest can push the price far higher for proof version, but the bullion coins are typically valued on metal content alone as an investment coin.

Smaller, fractional Britannia coins are also released regularly, with accordingly lower face values. In 2013 a larger £500 coin, containing five ounces of gold, was added to the range.

Generally speaking, if The Royal Mint make a 1oz gold coin they will denominate at £100 per tradition. This means other series, such as the new Myths & Legends series, are also classed as one hundred pound coins. Despite their gold value being much higher it is likely The Royal Mint will continue this tradition for many years to come.

£100 platinum coins

The Royal Mint also strikes Britannia and Beasts coins in platinum. These are denominated at £100, as are their gold equivalents. Platinum is growing in popularity as an investment metal, and is taxed similarly to silver; subject to VAT, but exempt from Capital Gains Tax when in the form of a one hundred pound coin.
