How about getting your dad an artifact replica or a model from the time period or civilization he is interested in? You could also get him a subscription to an archaeology magazine so he can stay up-to-date on the latest discoveries and research. Another idea could be to organize a trip to a local museum or archaeological site with him. If he enjoys reading, you could consider getting him a book written by a renowned archaeologist or a historical fiction book set in the time period he is interested in. Finally, you could get him a personalized Archaeology hoodie or a t-shirt with his favorite excavation site printed on it.
Or you can get him a star map with an important date you share.
