For your grandson who likes collecting trading cards, a great Christmas gift option can be a display case for his collection. This will not only help him store his cards but also showcase them nicely.
You can also consider getting him a starter pack of some new trading cards that he may not have collected yet, or some rare ones from his favorite game or sport.
Another idea can be a book on the history and significance of trading cards, which would not only be an enjoyable read but also help enhance his knowledge and love for the hobby.
Lastly, if you want to go for something fun and interactive, you can try getting him a board game like "Top Trumps" which is centered around collecting and trading cards.
Or you can get him a star map with an important date you share.
