I still have mine, although I don't know why I have kept them. They are buried somewhere in the attic. They are nothing to brag about so I don't show them to people. LOL.
I certainly would want to see them; I’m compiling information for a research project that I’ve undertaken. (Cough, cough.)

A couple of decades ago, I had to compile information for a job-related background investigation that was pretty intensive in scope, and it required me to provide proof of certain aspects of my education all the way back to high school graduation. I dug and dug and dug through old stacks of paperwork and was surprised to find my actual college and high school, which were accepted by the agency because they were certified documents. I put them away for safekeeping, and can now pull them up at a moment’s notice.
My mother may have kept report cards from my earlier educational endeavors at the elementary and junior high school level, I do not know.
