One idea could be to find a unique antique or vintage item that relates to one of his interests. For example, if he enjoys gardening, you could find a vintage plant stand or watering can. If he collects old clocks, you could try to find a unique one that he doesn't have. You could also consider getting him a book on antiques, or a subscription to an antique magazine or website so he can continue to learn and discover new pieces. Another idea is to take him to an antique fair or market where he can browse and buy something himself.
Or you can get him a star map with the date when he was born.
