10 Dollars Montréal Olympics, Hurdles

One of 28 silver issues struck across four series to fund the 1976 Montréal Games, this coin was part of a financing scheme that ultimately failed — the Olympic infrastructure ran so far over budget that Montréal taxpayers were still retiring the debt in 2006, thirty years after the closing ceremony. The Royal Canadian Mint sold the series directly to collectors at a premium, a strategy that generated revenue but also ensured most pieces never circulated.
