One great gift idea for your grandpa who enjoys stamp collecting is a personalized stamp album. You can purchase a blank album and customize the cover with his name and any other personalized details.
Another idea is buying a rare or hard-to-find stamps to add to his collection. You could also consider getting him a membership to a stamp collectors club or a subscription to a stamp collecting magazine.
Lastly, if your grandpa is interested in history, you could give him a book about the history of stamps or a book about the history of his favorite stamps.
Or you can get him a star map with an important date you share.
