Are these canisters just junk?

I'm really cleaning out everywhere in my house. Today, it's the basement. YUK!

I'm embarrased at how many things I bought, but never used.

I'm wanting to take about 7-8 Golden Harvest glass canisters to Goodwill. I've hesitated using them, since there's no "made in the U.S.A." on them, and they wouldn't be for food stuffs. (in my opinion).



But.......in trying to make sure they're not worth much, I've seen alot of "information" about them on places like eBay and Itsy, and they're saying they're "vinage". Haha...........I bought them at the Dollar General store for a few bucks each. I've searched all over to find out what company made them and where. Again, there's statements like "Anchor Hocking's Vintage glass canisters"........but I can't substantiate that anywhere. So.......I think I'll just send them to Goodwill.

Don't you think if I couldn't find who or where they were made, with no real identifying marks on the bottoms, I can't necessarily trust them with food? I doubt the best stuff is at Dollar General, right?
