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.
A rubber stamp of my grandfather’s initials, which happens to be exactly my initials.
Nobody else in the family have this initials, so this really would worth anything only to me.
