Almost 11,000 value changes were made in this year’s edition of Volume 5. Leading the way was Norway with more than 2,200 changes. In Russia, both classic and modern issues show substantial increases.
Other countries with a large number of increases include Papua New Guinea (860), North Borneo (802), Pakistan (484), Qatar (444), and Oman (438).
On the editorial side beginning with Volume 5, the break-point boxes noting the change from valuing hinged stamps to never-hinged stamps are now shaded in yellow so they can be identified more readily in the listings.
