Beschrijving keerzijde The central aluminium bronze core depicts an array of scientific instruments associated with the early research and isolation of insulin — including a glass vial, mortar and pestle, and an Erlenmeyer flask — overlaid upon a stylised maple leaf rendered in full colour. Surrounding these instruments are coloured representations of red blood cells, glucose molecules, and insulin molecules, the latter highlighted in vivid polychrome enamel. The initials JK appear in the lower field of the centre, referencing the historical figures connected to the discovery. The outer nickel-plated steel ring carries the bilingual inscription INSULIN / INSULINE and the commemorative dual dates 1921 and 2021, marking the centenary of insulin's discovery.

Aanvullende informatie

Canada's 2021 commemorative toonie marks the centennial of Frederick Banting and Charles Best's isolation of insulin at the University of Toronto — an achievement that transformed Type 1 diabetes from a death sentence into a manageable condition almost overnight. Banting sold the patent to the university for one dollar, explicitly to prevent commercial interests from restricting patient access.

The selective colorization applied to the centre planchet is production-applied at the mint, not an aftermarket addition — a distinction that matters for cataloguing purposes.
