I tried to clean an ancient Roman bronze coin of Constantius 11 (A.D. 337-361) a few years ago, by heating it, in an attempt to spall of some encrustations with differential expansion. It didn't work. In fact, when I cooled it rapidly by dropping it in cold water, it completely disintegrated into tiny black particles.   Total and instant loss of the coin. I won't do that again ! |

Pretty sure as a kid I squeezed a cent in my dad's vise once or twice.

There's a few good reasons not to do this, most importantly numismatics is about preserving coins, not destroying them.  I just never had any inclination to destroy a coin. Call me weird.  |

Call me weird for wanting to?  I wouldn't do that now, but whatever, not a big deal either way. Some of us didn't know any better at the time, I suppose. |

This post reminds me of one similar some time back. Many stories of how coins have been destroyed. Aside from my Chem experiments, I also put coins on RR tracks, tried to throw a Half Dollar across a river, placed coins on top of fire crackers, buried in wet concrete, etc.
One of my favorite dumb things was when I saw an add for so called Original Black Forest Hunting knives. The add claimed they would go through a Half Dollar. I purchased several of them and all they did was break trying to go through a Half Dollar.

Hey Carl, It was probably a 21-D Walking Liberty.

I've taken quarters and soaked them in pee for 72 hours, put them in the oven, tossed them in a campfire, put them in the microwave, burnt them with my dads blowtorch, had them ran over by a train, had them ran over by a car and much more

I experiment every time I go to Disneyland or on RV trips and it only costs me $0.51 but the results are always the same just different patterns... an elongated cent!

Cascade, you ever smashed a Zlincoln? I'm curious to see what the cladding does.

Not sure of other Zoo's but at Brookfield Zoo there are machines that take a Cent and smash it and put an Animal on it.

I have mashed both copper pennies and zincolns. The shield cent smashes the best  Except that the plating splits and it looks ugly. |

Year ago I got bored so I checked to see if fluber ( Borax, gule and water mixed) can destroy coins or tone them.
results.
Canadian:
striped off the top layer and rusted, thined out quite a bit. No toneing
American
alot more rusted then canadian, deep holes. Shiny yellow toneing with dots of purple.
Im kinda surprised that canadian took it better then american. I thought american coins are alot more beefer then canadian.

Wait I'm a tard, I was thinking u were taling about steel cents for some reason. Yes I have used zincolns. You don't really get the solid zinc showing through but it can show in the center and ends as a very slight rainbow ish type look and overall bright shiny almost pinkish copper
