The twelve 25 cent nickel coins of 1999 were issued along with the Millennium medallion of 1999, inserted in a replica of a 1785 map of Canada. The medallion was only available in the millennium set. All coins are brilliant uncirculated.
It is in this set that the “No Denomination” coins of September and November are found.
During the fall of 1999, a Queen Elizabeth II Caribou obverse die became paired with the reverse dies of September and November millennium twenty-five cent coins creating two mules. The interesting result of this pairing is that for the first time Canada has a non-denominational legal tender coin.
