All of the booklets up to BK13 seem to have sold for 25 cents. The stamps in BK13 add up to 72 cents. Did this booklet sell for 75 cents (3 quarters)? Did the machines that dispensed them have to be adjusted for this issue or were they sold only over the counter ? Booklets continued at 25 cents after that with the exception of BK39 ($1.00) until the Centennial Issue when larger format booklets were issued. Any help would be appreciated.
According to the Standard Catalogue of Canadian Booklet Stamps by Bill McCann, BK13 was issued on 6 Jan. 1929 with a face value and cost of 72 cents. So it appears that between Boggs and McCann we have a 1 cent discrepancy.
Thanks for the comments. So I assume this booklet was not sold in the machines that dispensed booklets. I remember there was one of these machines on the street corner near my house in the early 1960s. It was a convenient way to buy stamps if you had a quarter.
