One idea could be to take your grandson on a trip to an antique store or market. This would allow him to explore and potentially find some unique pieces to add to his collection. Alternatively, you could also look for online subscriptions to antique collecting or vintage magazines, or perhaps look for a book about the history and significance of antique collecting. If he has a favorite time period that he likes to collect from, you could try finding a replica or reproduction of a famous antique from that era. Additionally, you could also consider getting him a personalized antique item that has a special meaning or connection to your family history.
Or you can get him a star map with the date when he was born.
