The mint was founded in 1965 by Derek Pobjoy who purchased a coin press after leaving his father Ernest Pobjoy's jewellery and masonry business to set up a mint.^[2] Upon the death of Winston Churchill in the same year the small mint produced a series of gold medals to commemorate coins.

Since 1974, the mint has become involved in the production and international sale of new-issue postage stamps and currently exclusively coordinates the coin and stamp programmes of seven countries (Ascension Island, Bahamas, British Antarctic Territory, British Virgin Islands, Falkland Islands, South Georgia and South Sandwich Islands and Tristan da Cunha).^[2]

As manufacturers of gold chains, gilt and enamel badges and escutcheons, regalia and insignia of all kinds, the Pobjoy Mint has been contractor to the British Crown Agents and various London jewellers, for whom it has executed commissions involving precious metals and gemstones of all kinds.^[2]

On the 12th October 2023, the current Director Taya Pobjoy announced during a podcast with Coin World, a numismatic publication in the US both her retirement and the closure of the Mint in its entirety. The mint's website would remain open for orders but would also close in November 2023 with no further coins dated '2024'.

In the 1970s, the company developed a new metal alloy similar to German silver known as Virenium which consisted of 81% copper, 10% zinc and 9% nickel.^[3] This alloy has been used in non-circulating commemoratives since 1978.

In 1983, the company also created the Manx noble, a bullion coin containing one troy ounce of platinum. It was the first investment coin to be made from 0.9995 fine platinum. Its production ran for six years from 1983 to 1989. The noble has legal tender status although, like the South African gold Krugerrand, its value is defined only by its precious metal content as it has no numismatic value.

The mint also produced the Isle of Man's angel gold coin, from 1984 to 2016. In 1999, Pobjoy Mint issued the world's first titanium coin, the 1999 Gibraltar Millennium £5 coin.^[2]

The Pobjoy Mint has struck non-circulating (commemorative), circulating and pattern coins for nearly 20% of the world's governments and central banks as well as undertaking sub-contracted work for certain national mints. Many medallion issues have also been produced, notably for Hong Kong, Malaysia and the Arab States. The mint has produced eighty different medallions for the World Wide Fund for Nature collection.

The mint has struck coins for the following territories^[2][4]
