  • FIRST of three 99.99% pure silver coins in an exquisite NEW series called “Under the Sea” featuring some of the marvels found in Canadian waters!
  • An RCM FIRST: Mosaic murrini! The seahorse-shaped glass element is the result of a laborious handcrafted process in which different colours of glass rods (stringers) are layered and fused together to form a colourful mosaic that reveals the final image when sliced.
  • The handcrafted nature of both the murrini element and its glass enclosure make each coin unique.
  • Despite its delicate appearance, the glass embellishment is sculpted from borosilicate glass, which is highly resilient yet lightweight.

The reverse design by Canadian artist Maurice Gervais offers a glimpse of the hidden underwater world off Canada’s Atlantic coast, thanks to its depiction of a shallow sea grass habitat. The application of vivid coloured enamel over the detailed engraving recreates the textured rocks, seashells and swaying green grasses that line the sandy ocean floor. To the right, a handcrafted glass embellishment by Canadian glass artist Loïc Beaumont-Tremblay contains a striking seahorse-shaped mosaic murrini element. The mosaic-based approach to this glass art technique lends itself well to recreating the seahorse’s speckled colouring, while other features such as its bony armour, pointed snout and curled tail are equally captured in extraordinary detail. The murrini piece has its own “armour,” thanks to its resilient glass enclosure sculpted from borosilicate glass.
