ROYAL ASTRONOMICAL SOCIETY Meteorite 150th Anniversary 1 Oz Silver Coin 20$ Canada 2018

The reverse design by Alexandra Lefort is a re-interpretation of The Royal Astronomical Society of Canada's sesquicentennial logo in a scientifically accurate, photorealism art style. The original logo features stars that allude to Canadian contributions to stellar spectroscopy and photometry, and a globular cluster that honours the scientific work of Helen Sawyer Hogg and Canada's cooperative partnerships; both are colourfully re-imagined here as the Eagle Nebula—specifically the pillars of interstellar gas and dust known as the Pillars of Creation, where the formation of new stars is a symbolic representation of the RASC's beginnings (and by extension, its anniversary). All around the reverse, the inscriptions: "CANADA" – the issuing country, "1868 – 2018" – the years of Anniversary and the year of issue, "20 DOLLARS" – the face value. The obverse of the coin depicts the effigy of Her Majesty Queen Elizabeth II and the inscriptions: "ELIZABETH II" – the name of the Queen and "D · G · REGINA" – Dei Gratia Regina.
