Ps

Over time scribes combined the letters P and S into a single mark. Eventually the P disappeared leaving an S crossed by one or two vertical lines.

This evolved into the modern dollar sign:

$

Alternative Theories

1. Pillars of Hercules Theory

Some historians believe the symbol originated from the Spanish coat of arms featuring two pillars wrapped with a banner.

The design resembles an S-shaped ribbon around vertical columns similar to the dollar sign.

Another theory suggests merchants abbreviated US by placing the U over the S. Over time the U simplified into a vertical line crossing the S.

Although popular this theory lacks strong historical evidence.
