In addition to the mark at the top of the Queen's head, there is also some damage in the neck. As there is only one reported example, this must, for now, be considered non-constant. This variety does 'resemble' diagrams 1 PF 812 and 1 PF 813 in Ron Waldston's Plate Varieties of the Canada 1 Cent Small Queen, so finding additional examples is 'possible'.
