* Notes about these prices:
  • They are currently in beta mode, meaning that they should not be relied upon yet as a source of truth and could change frequently. Please notify CPS if you come across values that do not make sense.
  • They are not based on catalogue values but on current dealer and auction listings. The reason for this is that catalogues tend to over-value stamps.
  • They are average prices and might not be fully accurate. The actual value of your stamp may be slightly above or below the listed value, depending on the overall condition of your stamp.

About Stamp

Canadian scientists have helped to banish the darkness, to feed people better, to view the smallest objects, and to cure once fatal diseases. Scientists have treated cancer with radiation since 1896. Radium provided the necessary radiation until, with Cobalt 60, scientists discovered a source 300 times more powerful and 6000 times less expensive. The forerunners of today's Cobalt 60 therapy units were developed by Dr. Harold Johns in Saskatoon, and by Atomic Energy of Canada Ltd. These stamps, designed by Roger Hill of Toronto, mark the end of the three-year stamp series on Canadian Innovations in Science and Technology. The scientific achievements being honoured have been accurately rendered in a pleasing and precise illustrative style. Like the previous two issues which focussed on the themes of Transportation and Communications, this year's stamp designs features notes, drawings and diagrams on the development of each innovation on their backgrounds.
