Collector Research Notes

A commemorative design marking the 100th anniversary of the discovery of insulin by Canadian researchers Frederick Banting and Charles Best, featuring imagery related to the landmark medical breakthrough.

What Collectors Usually Check

  • This issue is tagged as scarce in the local catalog, so collector demand often depends on condition, eye appeal, and how often examples surface for sale.
  • Melt value gives you a useful floor for precious-metal content, but finished collector pieces can still trade at a premium based on packaging, scarcity, and market demand.
  • Original mint pricing provides issue-day context, but aftermarket pricing often moves independently once a coin sells out or enters the secondary market.
  • Use the listed edge, diameter, finish, and legends to verify the exact issue before comparing prices or catalog entries.
