Have plastic bags become antiques already?

At what point does something turn vintage and become valuable? Is it as soon as they become out of style?

Believe it or not there are people who are actually selling old plastic bags on the local Hudson Valley Facebook Marketplace.

It'd be nice to carry a few of these around and still use them. How much would you pay to bring back plastic bags? I do miss them but I will say that $10 is a bit steep.
