Sure thing. If they were pre-1982 pennies I would be ecstatic because those are mainly copper compared to "modern" pennies. Then I would drive to Mexico to start melting those bitches down so I could have $3 million!
Huh, interesting tidbit. I recall many years ago taking my propane-powered blow torch and melting a dozen or so pennies just to f--k around, heh. They're either tin or nickel depending on what's cheaper and if the melting temp of nickel was low enough for my blow torch.
I guess if it costs 2 pennies to make a penny then like Canaduh they should be discontinued. Or, make 'em out of plastic or something. That'd be cheap still and hey, those 3D printers will come in more handy.
Edit: Upon looking at penny trivia, the metal I thought might be tin when I melted some pennies was in fact zinc. From 1982 and forward they're being made out of zinc plated with copper. Too bad, I would've used the metal if it was tin for some soldering jobs of copper pipe... Makes sense, zinc has got to be much cheaper than something like tin.
