What is the origin of the $ symbol for the US dollar?
Strip of Eight Theory: This theory suggests that the "$" symbol evolved from the Spanish dollar's mark of value, which consisted of a vertical strip of eight lines. As the currency circulated widely, this symbol might have been simplified into the "$" sign.
Heraldic Coat of Arms Theory: Some theories propose that the "$" symbol is derived from the Pillars of Hercules, which were a prominent feature on the Spanish Coat of Arms. These pillars were often represented with a scroll wrapped around them, forming a shape similar to the "$" symbol.
