How about a subscription to an archaeological magazine or a book about famous archaeological discoveries? If your friend enjoys hands-on experiences, you could look into local archaeology courses or workshops or even a trip to a place with historical significance. Another idea is to buy them a replica artifact or a personalized piece of jewelry that is inspired by history or a specific archaeological discovery.
Or you can get her/him a star map with an important date you share.
