How about a personalized deck of playing cards with pictures of your family on them? You could create a custom deck on a website like Shutterfly or VistaPrint, and include pictures of your mom's favorite family memories or even some old family photos that she'll love. You could also include a nice set of card holders or a card shuffler to make her card games more enjoyable. Another option could be purchasing a brand new set of high-quality playing cards in a unique design that she doesn't already own, along with a book of new card games to try.
Or you can get her a star map with an important date you share.
