How about creating a custom trading card set that features your relationship milestones or special memories together? You could either design the cards yourself, or work with a graphic designer to create a snazzy illustrated set.
Alternatively, you could try finding rare or vintage trading cards that your girlfriend may not have yet. You could also look into buying her a subscription to a trading card service, where she could receive new and interesting cards each month. Finally, you could consider getting her a custom-made frame or display case so she can proudly show off her collection.
Or you can get her a star map with the date of your anniversary.
