A great gift idea for your dad's passion for collecting dollhouses could be a miniature furniture set or decoration for one of his existing dollhouses. You could also consider gifting him a new unique dollhouse that he doesn't already have in his collection. Another idea could be a book on the history of dollhouses or a subscription to a dollhouse hobbyist magazine. You could also plan a day trip to a local museum or exhibit featuring dollhouses and miniatures.
Or you can get him a star map with the date when he welcomed you in this world.
