But when Christopher Columbus came to America, the legend was changed to Plus ultra, meaning "further beyond". The Pillars of Hercules wrapped in a banner thus became a symbol of the New World . The link between this symbol and the dollar sign is more clearly seen in Spanish coins of the period - which show two pillars, each with a separate banner, rather than one banner spanning both pillars . In this example the right - hand pillar clearly resembles the dollar sign, and additionally directly relates to the use of money . </P>

Where did the us dollar sign come from
