For your dad's birthday, you can consider giving him a perfume bottle from a unique and rare collection that he does not have in his collection. Few other ideas include buying a glass display cabinet for him to display his collection, investing in bespoke perfume making experience where he can make his own custom scent and bottle it in a rare collector's bottle, or attending a museum exhibit featuring antique perfume bottles. Additionally, you can also consider giving him a book on the history of perfume and the evolution of perfume bottles, along with a bottle of his favorite cologne that can complement his collection.
Or you can get him a star map with the date when he was born.
