Some pennies are mostly copper and some pennies are mostly zinc. What happens to the different materials when they are cooled with liquid nitrogen and then hit with a hammer?
For those of you who think that what we are doing in this video is illegal, we direct you to Title 18, Chapter 17 of the U.S. Code (Coins and Currency). What’s forbidden is the ‘fraudulent alteration and mutilation of coins.’ There’s nothing fraudulent in what we are doing. We aren’t trying to make pennies look like dimes or something. There are plenty of (legal) machines at amusement parks and fairs that’ll happily smash one of your pennies into a souvenir. No one will send you to jail for that as long as you don’t try to pass it off as something that is isn’t.
No fraud, no crime.
