For face value and free shipping the newest commemorative 25 cent coins are available from the Royal Canadian Mint. You get 12 coins in total for three dollars and there’s a limit of two packages per household.
The coins’ reverses were designed by Bonnie Ross (Arctic Expedition) and Tim Pitsiulak (Whales). There’s already rumblings of some varieties amongst these designs too.
At face value, you can’t go wrong, but these do sell out quickly!
