One idea is to get her a shot glass display case that she can use to showcase her collection. You can also consider getting her shot glasses from different places she's traveled or that have a special meaning to her. Another option could be to arrange a "shot glass of the month" club, where she would receive a new unique shot glass each month for a year.
Or you can get her a star map with the date when she was born.
