Pennies are legal tender. It’s just no one bothers prosecuting stupid little penny-smooshing machines.

Pennies aren’t legal tender, and thus, aren’t protected under the law. Or so I’ve been told. That’s why there aren’t any nickel stamping machines at those tourist traps.

I was going to try this but I ending up using all of my caustic acid last week when I was being put on trial by a crusading District Attorney.

Sorry, I tend to skip over text when I see something thats either silly or nonsensical.

Its that habit that has allowed me to read Ron Paul’s Revolution: A Manifesto in under 20 minutes.

Zen:
a) I mentioned penny-smooshing machines.
b) I’m pretty sure the penny already contains more than a penny’s worth of materials, with the copper and zinc.

Defacing US currency? There are penny mills that stretch and imprint pennies with the image of the Statue of Liberty at the Statue of Liberty.

Besides, with the US dollar continuing to depreciate and with copper prices climbing, eventually, the copper in the penny will be worth more than the penny itself.

I’m pretty sure this technically illegal, fwiw, at least here in the U.S. Defacing US currency and what not. (I wouldn’t worry about it, though- there are plenty of publicly available machines that smoosh pennies floating around.)

This was a pretty standard high school chemistry experiment for me. Did you guys not do this?

Any laboratory supply house, many pool and spa care houses, and many hardware stores, as it’s an ingredient in most de-liming cleaners (read the labels first, as it’s often not the only ingredient and some of the additionals may mix badly with metals.) It’s also sold as muriatic acid. Wear safety goggles and nitrile gloves (they tear less easily than latex rubber gloves)

I once bought hydrochloric acid from a guy who told me it was the fun kind of acid… It was not.

Like everything else, you can get it over the internet.
