noun a former United Kingdom silver coin; United Kingdom bronze decimal coin worth two pennies
originBy surface analysis, two + pence, collective plural of penny. Same for the definition: "Ellipsis of tuppence worth (“one’s opinion”)" however, this idiom is derived from this fact; in Britain it used to cost two pence ("tuppence") to post a letter, usually holding one's opinion.
