One idea for an anniversary gift for your husband who likes collecting badges or patches could be creating a custom shadow box to display his collection. You can buy a shadow box frame and then carefully arrange all of his badges and patches inside.
Alternatively, you could also consider buying a personalized plaque or display case with his name or initials engraved on it to highlight his collection. You can also consider getting some rare or hard to find badges from his collection to add to his collection.
Lastly, you could also surprise him by taking him on a special trip to attend a collectors' fair or a badge trading event where he can meet fellow collectors and add to his collection.
Or you can get him a star map with the date of your anniversary.
