It was the "throw it out, it's trash" mentality that has destroyed countless bottles that collectors in the future would pay a premium for.
You could always post them in the "What is it?" section, even a picture of a bunch of them is often enough to identify several at a time. If some stand out we can ask for more photos.There’s a handful of this sort lying around in my collection, I’ll make a box of them and maybe I can hand them out to kids at a yard sale like you said.
By the way, this is rather off-topic, but what’s the best place to show my collection and possibly get some insight on certain bottles? I haven’t really taken collecting seriously until this year, I have ~40 bottles to date and some I’m stumped on.
De-clutter your life and dump those in the recycle bin.
