Henry VII piece that is on offer at Royal Mint (Image: ROYAL MINT)
Napoleon's ultimate ambition was to invade England with around 100,000 men from the northern coastal city of Boulogne, but his attempts were crushed by Britain's superior naval might.
Although he failed, he is considered one of the greatest generals in history, with the Duke of Wellington - who helped defeat him in the Battle of Waterloo - arguing “his presence in the field made the difference of 40,000 men".
Yet, had Napoleon gone on to claim victory and seize England, the future of the country's currency - and that of Royal Mint itself - could have been completely different.
