You could consider getting your mom a Bach music box. Another idea would be to create a Bach-themed gift basket, including a compilation of his music, a book about his life and legacy, and perhaps some gourmet chocolates or other treats to enjoy while listening to the music. If your mom is musically inclined herself, you could also consider getting her a Bach sheet music book or tickets to a Bach concert in your area.
Or you can get her a star map with the date when she was born.
