Hi Arthrene,
I have one here - it has 4 'pages'.
Pages 1 and 2 to fit the 1 cent coins; pages 3 and 4 for the 2 cent coins.
Page 1 has 16 (labelled) slots for 1c pieces from 1966 to 1981
Page 2 is labelled from 1982 to 1991 with an extra 6 unlabelled slots.
Page 3 and 4 are the same but with larger slots to fit the 2 cent pieces.
hope that makes sense!
Anna
