My mother did not give mine away, she threw them away!
I put a stop to that, but many of my oldest and most valuable ones were destroyed.
(A couple of years ago, a family that was about to lose the generational home found in the attic on their last day an old comic book: Action #1. They sold it for $1,000,000 and saved the home.)
I am so deeply sorry about your collection. It never makes it through my head how someone who loves you so much, like a mother, could not understand how something could mean something to you, even if it doesn’t mean something to them.
