How about a stamp collecting album or a stamp display case so she can organize and showcase her collection? You could also consider getting her a set of new stamps from different countries or eras to add to her collection. Another idea could be a book about the history of stamps or famous stamps from around the world. If she's into DIY projects, you could also consider getting her a stamp kit so she can create her own custom stamps.
Or you can get her a star map with an important date you share.
