Could be an attached memory or sentimental value, whatever.
Conventional worth be dammed.
Given to me it would either be the quilts my grandmother made, or the charts my grandfather followed along with during the moon landing.
Personal items would be the assorted thank you notes the elderly have given me from being in retirement industry. Want to make a collage of them one day.
My mother’s wedding ring. My father was a monster, so it’s not because of the marriage it represents. It was the cheapest he could get, it’s thin and worn down and battered, and, of all the kids, she gave it to me. When I die, however I am disposed of, that ring goes with me, because… she gave it to me!
