At least you DO get to see these coins in circulation in Canada. In the UK we have had an avalanche of new 50p and £2 coins since 2016 that haven’t been issued for circulation, and we can’t get loose 38mm cupro-nickel £5 coins for face value from the banks any more – we have to pay about double face value and order them from The Royal Mint, Westminster Collection or the Koin Club.
