How many pennies were there in one groat (an old English silver coin)?

The groat is the traditional name of a long-defunct English silver coin worth four English pennies, and also a Scottish coin originally worth fourpence, with later issues being valued at eightpence and one shilling.

It was after the French silver coin had circulated in England that an English groat was first minted under King Edward I. Scots groats were not issued until the reign of David II.

The groat ceased to be minted in the United Kingdom in 1856, but in 1888 a special request was made for a colonial variety to be minted for use in British Guiana and the British West Indies. The groat remained in circulation in British Guiana right up until that territory adopted the decimal system in 1955.
