On stamp yearbook

Of course, stamp yearbooks are valuable for collection. They record the major events that happened in a year, but the collection value of yearbooks is not great. Stamp yearbooks in recent ten years are more valuable for collection, such as 2003, 2006, 20 10, 2000. It's best not to buy stamps from the 1990s. Stamp yearbooks from the 1980s are more valuable, especially those from 1987, but these are rare. If you encounter it, you should collect it quickly.
