Global Money Week – “From Barter to Banknotes” - Global This silver 8 Reales of Charles III is arguably one of the most important coins in financial history. Known globally as the "Spanish Dollar" or "Piece of Eight," this massive silver coin was the first truly global currency, accepted from the markets of Canton to the ports of the Americas. Its consistent weight and purity made it the unofficial reserve currency of the world for over two centuries, even serving as legal tender in the United States until 1857.
