Commonwealth Games Coin

Here we have a commemorative coin celebrating "The Miracle Mile" at the 1954 British Empire and Commonwealth Games held in Vancouver. It features Roger Bannister and John Landy. The flip side shows Dr. Doug Smith at the 1978 Commonwealth Games in Edmonton. This is a great piece of sports history! I'd say its worth around $20, based on similar listings on Kijiji. Just trying to declutter and spread the joy!
