2025 225th Anniversary of Australian Proclamation Coins Pillar Dollar 1oz Silver Coin

Although it remains a topic of considerable numismatic debate, a Proclamation coin is usually defined by its inclusion in Governor Philip Gidley King’s famous edict of 19 November 1800, which attempted to solve the currency crisis afflicting the colony of New South Wales.

In response to the ongoing shortages, 40,000 Spanish reales were brought into the colony by Governor Lachlan Macquarie in 1812. A decision was made to increase the number of available coins by cutting out the centre of each coin. The coins then underwent a counter stamping process, designating the outer ring as the ‘holey dollar’, and the centre as the ‘dump’. This operation prevented the coins from being exported and led to the creation of the first currency minted in Australia.

The 2025 225th Anniversary of Australian Proclamation Coins – Pillar Dollar 1oz Silver Bullion Coin is struck by The Perth Mint from 99.99% pure silver and issued as legal tender under the Australian Currency Act 1965.

This coin has a maximum mintage of 30,000.

DESIGN

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.

Included in the design is a unique ‘Mo’ mintmark, indicating the coin’s origin from Mexico City. This design element pays homage to the tradition of Spanish Empire coins bearing distinct mintmarks signifying their minting location.

The obverse depicts the Dan Thorne effigy of His Majesty King Charles III, and the monetary denomination.

The coin incorporates an authentication feature on the reverse. In the form of a micro-laser engraved letter, it is only detectable under a magnifying glass.

ABOUT THE PERTH MINT

The Perth Mint, located in Perth, Western Australia, is one of the oldest and most prestigious mints in the world, with a rich history that dates back to the late 19th century. It was established in 1899 as a branch of Britain's Royal Mint in response to the discovery of rich gold deposits in Western Australia. Its primary purpose was to refine gold mined in the region and to mint gold sovereigns and half sovereigns for use throughout the British Empire.

The Perth Mint played a crucial role in the development of Western Australia's gold industry, providing a local facility for gold refining and coin production that significantly contributed to the economic growth of the region. Over the years, it has evolved to become a leader in the precious metals industry, offering a wide range of services including gold and silver bullion bars and coins, precious metal refining, and jewellry.

After Australia gained independence, the Perth Mint continued its operations and, in 1970, it became wholly owned by the Government of Western Australia. Since then, it has expanded its offerings to include commemorative coins, investment products, and a wealth of services for precious metals storage, management, and distribution.

Notably, The Perth Mint has set several world records, including producing the world's largest gold coin in 2011, weighing one tonne and featuring a kangaroo design. It also operates one of the largest LBMA (London Bullion Market Association) accredited gold refineries in the world.

The mint is also a significant tourist attraction, offering visitors insights into Australia's gold mining history, the chance to view Australia’s largest collection of natural gold nuggets, and live demonstrations of traditional gold pouring.

Swan Bullion Company is proud to be an authorised distributor for both The Perth Mint bullion and numismatic products.
