Since I already wrote a post on the debasement of coinage during Henry’s reign, I thought I’d look up a little about coining methods, techniques and laws regarding minting during the time. At a time when there was no paper money, and certainly no plastic money or electronic money, mints were used exclusively for making coins from different metals.
Coins were produced in Roman Britain, but an English mint was only set up around 650. The mints were held by many different individuals as businesses, but eventually, by the reign of Henry, they had all consolidated into one single mint in London. Considering that the mint was held by the king, it was just added to the royal treasury. It produced copper, silver or gold coins in the name of the King and received a portion of the metal as seigniorage. Seigniorage was a kind of royalty paid to the mint for services rendered.
