Royal Mint's biggest coin in history unveiled

The enormous coin is too big for one hand alone and took hundreds of hours to produce and polish.

The Royal Mint has produced the largest coin in its 1,100 year history - measuring 20cm wide and 10 kilograms in weight.

The coin, which has been described by Mint as a "masterwork" and has a denomination of £10,000, took a whopping 400 hours to produce - including four days of polishing.

Only one original was made and has already been sold for a six-figure sum to a deep-pocketed mystery buyer.

Those with on a tighter budget can opt for a £13 version, which has a denomination of £5.

The production process combined traditional and more innovative coin manufacturing technologies, such as engraving machines to cut the intricate design.
