A Functional Sundial in Pure Silver
The reverse, designed by Canadian artist Anna Bucciarelli, transforms the coin into an actual working sundial.
At the centre is a raised gold-plated brass gnomon, surrounded by elaborately engraved Roman numerals and decorative elements. When the coin is placed on a flat surface in direct sunlight and correctly oriented toward true north, the gnomon casts a shadow that can indicate the approximate local solar time.
A beautifully detailed sunflower appears at the base of the design, symbolising the sun and its life-giving energy.
