That's a great interest to have! Here are a few gift ideas for your grandpa:
1. Custom display case: Consider buying a custom-made display case to showcase your grandpa's badges and patches. You can find display cases in various styles and materials online or at your local hobby store.
2. Vintage patches: Take your grandpa on a trip down memory lane by finding and gifting him vintage patches that relate to his hobbies or interests. You can look for these patches on eBay or at thrift stores.
3. Personalized patch or badge: Consider creating a personalized patch or badge with your grandpa's name or initials on it. You can easily find services online or at local embroidery shops that can make custom patches.
4. Badge collector guide book: Opt for a coffee table book which would serve as a guidebook for badge collecting. Your grandpa can flip through the book and discover new badges and patches to add to his collection.
5. Badge subscription box: Buy a monthly subscription box offer which is specifically made for badge collectors. This provides an opportunity for your grandpa to receive new and exclusive badges every month to add to his collection.
Or you can get him a star map with an important date you share.
