Pennies made before 1983 are 95% copper. The amount of copper in these pennies is actually worth 2.2 cents!

Could someone help me out?
The Thing at the top of the page says that it is ILLEGAL to do this to a US penny... but i was under the impression that you can do anything with your money because it is just that... YOUR money. Once you have it, you can do whatever the hell you want with it... I thought (this may be from a History Channel program about money), that once its yours you can write on it, burn it, rip it, whatever because it's your fault that you just lost x-amount of money for doing that.

moneyman is correct. Amie is wrong. What may have been an old law waas repealed and once you posess your money, you can destroy it or alter it if you wish, unless you desire to transform the money in an effort to pass it off in a fraudulent way. In which case yo ass goes in front of da judge!

stomach acid is technically hydrochloric acid, but only in the sense that michael jackson is a male. stomach acid is diluted with pepsin (enzyme for digestion) and, of course, whatever crap you shoveled down a few hours ago. even if you starve yourself, it still wouldn't work, because the body is designed to stop the hydrochloric acid from burning a hole through your gut. so yeah jcrk09...go knock yourself out. ;)

Well, the body is not designed, the mucus surrounds the stomach to prevent it from burning a hole through it, who ever thought that boogers are good ? LOL any way I mean the the whole stomach has a layer of Mucus that prevents the acid from coming out...
