Congrats on getting out! And you found the bane of our existence! The good 'ole pop top! I think those should be made out of gold then we wouldn't mind finding them! lol!
I found some of those and the screw caps, some clad, and a fake ring that had me going for a minute. I would post pics but I'm e-challenged!
Stuff them, along with the aluminum cans, can slaw and the millions of their cousins, in a big trash can. When the can is full, you have a few sets of free batteries, and maybe even some beer.
