Very good point. I will clean them up and put them in storage, maybe I can set them out at a yard sale someday. And it looks like I'll have to get a little better at dating bottles. I was just going by the seam on these but I think it's fair to say it may have just eroded away for some of them.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.
