I have a few items from one of my grandfathers. He belonged to a US armored division on the European front in WWII. His souvenirs included a spent 75mm tank/artillery shell, making my collection of fired brass both small in number and large in mass. I also have a Nazi bayonet and an Iron Cross medal he somehow acquired.
From the other side of the family, I have a very utilitarian pocket watch that belonged to that grandfather and some items my grandmother made for me, like a pillowcase and I think a small blanket I had as a child. Very mundane, but more meaningful as a result, don't you think?
I like your items and am sure they'd carry a lot of personal value. I like the pillow case/grandma stuff a lot and as you say they are meaningful indeed, a tangible link to a person, someone who made those items. I have a few such things of my own and have some others that are meaningful to my siblings for safe keeping as well.
I can't single out a single item that is my favourite or most meaningful, they're all of great value and I treasure them.
