Struck by the Royal Australian Mint from one troy ounce of 99.99 percent pure silver, this proof coin marks the centenary of the birth of Queen Elizabeth II. The reverse brings together her royal cypher, a stylised St Edward's Crown and floral tributes including roses, lily of the valley, myrtle and golden wattle, alongside a horse and corgi nod to her lifelong companions. It comes encapsulated in a presentation case with a certificate of authenticity, making it a fitting addition to any Australian coin collection.
