The Dollar Sign: Origins, Theories, and Global Notation
About this episode
A concise tour of how a two-stroke symbol moved from peso ledgers to the US dollar and onto currencies named dollar or peso. We weigh the main origin theories, peek at printing-era experiments, and explore the cifrão’s unique role as decimal separator in Portuguese-speaking worlds. A quick dive into history, tradition, and the digital age.
