A penny is worth a bit over half a cent. http://www.coinflation.com

Around 2010 or so a Nickel was worth close to 6 cents. I don't think melting them down for profit would've been scalable. You could freeroll them (sock away $1M worth, hope the metal price goes up, if it doesn't you still have the cash value), but I don't think that's efficient either due to the combination of inflation, the relative unlikelihood of big returns on the metal value, and the expenses around acquiring, transporting, and storing/securing the coins.
