A quote about the coins and origins
The term Arnprior was first applied to 1955 silver dollars with only 2 and 1/2 water lines in front of the Canoe (actually one of the water lines is part of the island), with no trace of a fourth waterline. Some of these 1955 Arnprior die dollars have a die break between the T and I of GRATIA in the obverse inscription. Coins struck by cracked dies have this crack showing as a raised line, usually in the field. These die break examples are considered to be the original due used for the examples that were distributed at Arnprior, Ontario.
They were struck when a business in Arnprior, Ontario ordered dollars for a giveaway to its employees, at a time when the mint had none available. To fill the order, the mint took out and re-polished a slightly worn reverse die, removing part of the water lines in the process.

I agree.

The truth is, so little of importance happens in Canadian Numismatics, we tend to name everything. If this were US numismatics, we'd now have the "zebra Deluxe woody half plated" steel war penny or something because we'd run out of cute names.

Arnprior Dollar, EWL Five Cent and so on.... none of them tell you what's actually going on with the coin. My favourite name though is "New Zealand Mule" . That one is actually accurate.
