Maybe you can talk her into showing you how to cook one of your mom's favorite dinner recipes while she is there.
I hope you and she have a good time sharing memories.
When my dad died a few years ago, I had to go through his things and narrow it all down to what I could afford to ship back home to California. Ended up with three large boxes of photo albums, sentimental knickknacks, some of his army medals and memorabilia, and a few of his shirts that still have his scent on them.
I never opened them until I got to New Mexico. It took me two years to be able to go through all the photos and divide up things with my brother. I laughed a lot at what I initially chose as having significance and wished I'd kept some other items. Lots of tears and remembrances too.
Take your time, go slow and share the emotions when you need to, my friend.
