Conclusione

Currency symbols provide quick visual recognition, while ISO codes ensure unambiguous identification—essential quando multiple currencies share il same symbol. Il dollar sign ($) alone potrebbe mean over 20 different currencies, so international contexts require either ISO codes (USD, CAD, AUD) o qualified symbols (US$, C$, A$). Comprendere both systems helps navigate global finance, travel, e international business.
