The coin’s reverse pays homage to the Spanish Pillar Dollar, also known as a peso, or a ‘piece of eight’. Under the inscription ‘VTRAQUE’ (meaning 'both are one'), the coin portrays the Spanish Crown and two hemispheres representing the Old World and the New World. These elements are surrounded by representations of the Pillars of Hercules, both draped in spiralling banners displaying the words ‘PLVS VLTRA’ (meaning 'more beyond'). It has been suggested that the s-shaped configuration of the banners around the columns explain the origin of the ‘$’ sign. Also on the reverse is the 2025 year-date.
