A great birthday gift for your husband who likes collecting badges or patches would be to create a custom shadow box display case filled with his favorite badges or patches. You could include a few new ones that you know he will appreciate, and also add a personalized plaque to the display to make it more meaningful. Another idea could be to surprise him with a visit to a local antique or vintage store that sells patches or badges, and let him pick out some unique pieces to add to his collection. Lastly, you could consider getting him a subscription to a badge or patch trading platform where he can connect with other collectors and expand his collection.
Or you can get him a star map with the date when he was born.
