One idea could be to get him an autograph from his favorite celebrity, athlete, or musician. You could try searching online for signed memorabilia from reputable sellers or even reach out to the celebrity's team or management to request an autograph. Another idea could be to plan a trip to a convention or event where they have autograph signings, giving your boyfriend the opportunity to meet his favorite personalities in person and get their autographs. Additionally, you could consider getting him a framed display case or book to store and showcase his collection.
Or you can get him a star map with the date when he was born.
