I figure that a blank 'cents' book will hold all of the canadian cents from 1937 - 2011, plus 15 blank slots. This would account for all of the George VI (37-52), and the current Elizabeth II (53-). The extra 15 slots you could use to show individual coins. I use these to show the four faces of Elizabeth II and the George VI including and not including IMP IND, denoting the Emperor of India. I'll put a George V there, if I ever find one.
