Overview

Josh and Chuck explore the fascinating origins and meanings behind major currency symbols including the dollar, euro, pound sterling, yen, yuan, and rupee. They trace how these symbols evolved from abbreviations and historical traditions, revealing surprising connections like the dollar sign's roots in the Spanish peso and the pound sterling's status as the world's oldest continuous currency dating back to 928 CE.

The Dollar Sign: From Spanish Peso to Global Symbol

The dollar sign has a surprising origin story that traces back to the Spanish peso from the 15th century, also known as pieces of eight. The United States modeled their dollar after this peso, and the iconic $ symbol evolved through a series of space-saving abbreviations. What started as 'P.S.' for peso eventually became the symbol we know today, with both single and double vertical line variations in use.

  • The dollar comes from the Spanish peso de ocho (pieces of eight) from the 15th century
  • The dollar sign evolved from abbreviating 'peso' as P.S., then writing S over P, then removing the round part of the P
  • There are three iterations of the dollar sign, with the double vertical lines through the S being the most recognized
  • Ayn Rand falsely claimed the two lines represented U and S for United States
  • Twenty countries use the dollar, designated by country initials like U.S. or C.A.
" I can really save some space if I wrote the S over the P. Someone else came along and said, you know what? We could save even more space if we got rid of the round part of the P. And someone else said, oh, my God, you guys just created a dollar sign. "
" I think it's such a great burn that Canada adopted the dollar and abandoned the pound. Way to go, Canada. "

The Euro: Europe's Mysterious Modern Currency

The euro is one of the world's newest currencies, launched in 2002 after the European Union formed in 1992. Its symbol features a curvy E with two horizontal lines representing stability, based on the Greek letter epsilon. In an intriguing twist, the EU has never revealed the identity of the designer who created the euro symbol, leading to playful speculation about the mystery.

  • The euro wasn't introduced until 2002, making it one of the newest major currencies
  • The symbol is based on the Greek letter epsilon (E for Europe) with two lines representing stability
  • The Euro designer has never been revealed by the EU
  • Originally launched with seven banknotes and eight coins
  • Banknotes are identical everywhere, but coins have a common design on one side and country-specific designs on the other
" I suspect it's because it's an American and they hadn't looked into the person's background yet when they hired him. And I also suspect that that American is Eddie Money, which is why they hired him in the first place. "
