Have you ever heard about the Decimal Day? It happened on 15 February 1971. On this day, the UK changed its money system to a simpler, decimal-based way. This means it started using groups of 10, just like our normal numbers. Before Decimal Day, British money was a fascinating mosaic of historic coins. Here’s a quick guide: The Core System (£sd): 🟢£ (Pound): Not originally a coin, but a unit of account worth 20 shillings. 🟢s (Shilling): A silver coin. 20 shillings = £1. 🟢d (Penny): From the Roman denarius. 12 pence = 1 shilling. Key Coins: 🟠Farthing: A small copper coin worth ¼ of a penny. 🟠Halfpenny (pronounced “hay-pny”): worth ½ penny. 🟠Threepence (pronounced “thrup-ny”), a small silver (later brass) coin, 3 pence. 🟠Sixpence: A silver coin, 6 pence. 🟠Florin: Introduced as a step toward decimalisation, worth 2 shillings (24 pence). 🟠Half Crown: A handsome silver coin worth 2 shillings and 6 pence. 🟠Crown: Worth 5 shillings. The Special One: 🪙Guinea: A gold coin worth 21 shillings (£1 1s). Even after it stopped being minted, it remained the currency of prestige—used for professional fees, luxury goods, and racehorses. In a nutshell: It was a duodecimal system (based on 12s and 20s). A price written as £2 3s 6d meant 2 pounds, 3 shillings, and 6 pence. Quaint, complex, and full of history!🇬🇧 #countrystudies_olympiadenglish #countrystudies
