How about gifting your husband an antique from his favorite era or object that he has been searching for a long time? You could visit antique shops, auctions, or online stores that specialize in antiques and find a unique piece that would make his collection more complete.
Alternatively, you could also consider gifting your husband an experience, such as a trip to a historical town or museum that showcases a collection of antiques. This would allow him to explore and appreciate his passion for antiques in a new and immersive way.
Another idea could be a gift card to an antique store, which would give him the chance to peruse and choose a new piece for his collection at his leisure. This way, he can pick out something that he really loves and add a personal touch to his collection.
Or you can get him a star map with an important date you share.
