Incorrect.. It's Doubled Die Quote - "Note that the proper terminology for this occurrence includes the letter 'd' at the end of the first word, hence "doubled die". The term "double die" without the first word ending in 'd' is not proper numismatic terminology." closed quote https://en.wikipedia.org/wiki/Doubled_die
To learn more about Canadian Large Cents I highly recommend Rob Turners book “Dies and Diadems”. Link to the best site on Victoria Cents...... http://www.victoriancent.com/
It's not a doubled die actually, just a re-engraved or re-punched letter. Quite common on 19th century Canadian coins, especially the 1 cents. You can see the first A was set a little too high in relation to the other letters. Quality control caught it.
Thanks for all the input. The reverse had couple breaks in the grape vine, grease or debris in the die, not dramatic. The date had no interesting features. I appreciate the info on the re engraving of the "A", so much to learn.
