2. A rare or vintage pin from a place or event that is special to him.
3. A subscription to a monthly pin club that sends a new pin every month.
4. Custom-designed pins that reflect his interests or hobbies.
5. A book on the history of pins or button collecting, which could be a great addition to his collection.
I hope this helps!
