How about a custom-made cosplay costume for your grandma's birthday? You can either source this from a professional costume designer or make it yourself as a thoughtful gesture. You can also buy her some accessories that complement her cosplay costumes like wigs, jewelry or other items that can be used for her future cosplay events or photo sessions. Alternatively, consider a book on cosplay history or technique or tickets to a local cosplay event or convention. Depending on her skill level, you could also consider a sewing machine or fabric to help her create new costumes.
Or you can get her a star map with the date when she was born.
