Pennies = Luxury?

In my university chemistry class, my instructor mentioned to us about pennies and the industry completely halting on minting them, so people who still have pennies lying around would be one of the "luckiest" to have something that would otherwise be impossible to find or acquire because the industry stopped minting pennies.

This made me realize that pennies could be seen as luxury more than as some basic-ass "souvenirs" that you only purchase for display. As a child, I've heard of the "lucky penny" trend where you'd be given 24 hours of good luck for every penny you find and pick up, and I think this might've predicted pennies not being minted anymore.

I guess the follow-up question would be this: how much do you guys think pennies are worth after they've stopped being minted? Like, if you for whatever reason sold these pennies that you had lying around, how much would they sell for as rare "assets"?
