Groat or Fuppence is the name of an old English coin. The term literally means great, and was applied originally to large copper coins worth more than a penny. In the reign of Edward III a silver groat of the value of eight cents was coined. Three groats made a shilling. It has not been coined since 1856. Like the American cent, the term has passed into proverbial use to denote a small sum or little value. It appears in "Not worth a groat," "I care not a groat," etc. The term groats, applied to hulled oats or meal used for food, is of very different origin, being allied to grit.
