process of how a penny gets rusted?

Pennies can't rust.  The chemical composition isn't right.  Rust is Ferric oxide and ferric is iron.  A penny contains, primarily, copper.

A penny with a hole in it is worthless because you can't spend it, so it is hopeless - there's no help for it since you obviously can't fix the hole in the penny. That's what it means. I don't know the origin though - sorry! Will look it up first and I'll get back to you if I find it.

It is chemical change. The material ( generally metal) gets oxidised when left in air and this is termed as rust.

1944 copper wheat penny I think.

we had a old trick years ago .. get a 2pence or a penny and put it you know where , if they react to it there is a problem if they say nothing your normally ok ( not for teating aids ) .. what happens the copper reacts with the woman and will cause her dicomfort if she has anything . if the coin turns green run like hell , if you think you have a new coin run like hell .....

It loses electrons, so it gets a higher oxidation state. An example would be iron going to rust (Fe(s) --> Fe+3).

it depends on: if the american pennies are:  steel, aluminum, or copper.  Thank You.  anymore trick questions?\n I have the answers  :)

if metal rusts, the iron is being oxidized so it is a chemical change.

Hi Underworld -- I'm afraid some of the previous answers may have caused some confusion about the coin(s) in question... So -- let me explain it like this:\n\nYour 1940 penny is likely worth .02 to .05 (cents) if in "pocket-change" condition.  If it is still in "shiny new" condition, perhaps $1 to $1.50.\n\n . . . ABOUT WHEAT PENNIES . . .   (per Coinfacts.com)\n\nMost Wheat cents are very common, and were produced by the millions and even billions. Currently, common date wheat cents carry a very small premium, in fact only a few cents to a few dollars each, depending on condition and year. Be on the lookout for the 1909-S, 1909-S V.D.B. (The designers initials that appear at the bottom of the reverse), 1914-D, and the 1922-D with no mintmark below the date. These four dates carry a nice premium if you have one. Wheat cents may be a good start to a youngster's collection.\n\nA complete list of Wheat Cents and their retail values is available in the Guidebook of US Coins by R.S. Yeoman. Currently you can purchase the Guidebook of US Coins for as little as $11 online (see link below)\n\n===========================\n\nThe reference to a 1943 penny with a "value of 200,000" is incorrect...  \n\n . . . ABOUT 1943 STEEL PENNIES . . .  (per Heritage site)\n\nIn 1943, the production of our One Cent coin went through a major change. War efforts that year required copper and its availability was limited. It was decided to change the content from copper to steel coated with zinc for the first run of the new 1943 cents. In 1944, the need for copper was reduced, and the production of the copper cent resumed.\n\nOver one billion 1943 steel cents were produced at the Philadelphia, Denver, and San Francisco mints, making this a very common coin. However, many people found the new "look" fascinating and saved, rather than spend, the new steel cent. Today, their value ranges from about 5 cents up to about 35 cents in circulated condition. Uncirculated specimens (showing no trace of wear or handling) can bring up to about $10 in high grades.\n\n===========================\n\n . . . ABOUT 1943 COPPER PENNIES . . .\n\nRare errors on bronze planchets are known - BUT beware of counterfeits (bronze will not be attracted to a magnet). IF you happen to locate a BRONZE colored 1943 penny - take it to a coin dealer THAT YOU CAN TRUST for their opinion.  \nGenuine cents of this type can sometimes fetch $40,000.00+.\n\nWhy the confusion?\n\nMany national and area television stations recently reported about a $500,000 cent. They mistakenly advised people that the steel cent was very valuable. What they should have said was that THE 1943 COPPER CENT IS THE RARE VERSION.\nWhat happened was an extremely limited number of 1943 cents were inadvertently struck on copper planchets, left in the machinery from the previous year. Very few escaped the mint unnoticed, and these are considered very desirable to collectors. \n\nAuction histories indicate the value range to be from around $5,000 to $70,000 depending on the mint and condition... not the half million-dollar figure quoted. Copper-plated zinc forgeries abound. The primary test is to use a magnet. The common steel & zinc pieces (and the copper-plated fakes) will stick to the magnet. The rare copper issues will not.\n\n[I also found this info about this coins' value:  A 1943-S Copper Cent (graded NGC MS-61 Brown) sold for $115,000 in Ira and Larry Goldberg's "Dr. Jon Kardatzke" sale, February 6-8, 2000, Lot 257 (ex - Superior's "Dr. Charles Ruby" sale, 1974 - Steve Benson, sold privately for $49,500.00 - Superior, June 2-3, 1997, "ANACS AU-58"]\n\n===========================\n\nSuch is the world of collecting coins....good luck to you.\n~mishel

As a coin collector, I highly recommend **against** cleaning a coin by any means other than a soft cloth.  If you clean a coin using any acid or solvent, you destroy protective coatings and etch away the metal of the coin, thereby reducing its value.\n\nAs a chemist and a coin collector, if you absolutely, positively MUST clean the coin for some reason, I suggest a very mild baking soda solution and a soft cloth, followed by careful rinsing in clear water.

Quarters, dimes, and half dollars are cupro-nickel clad. Each coin has a copper core and an outer layer, the “clad,” made of 75 percent copper and 25 percent cupro-nickel alloy. Nickels are made from the same 75-25 alloy. The Golden Dollar is also a clad coin. The alloy layers on each side of the copper core are manganese brass, a golden-colored material composed of 77% copper, 12% zinc, 7% manganese, and 4% nickel. The cent, once a copper coin, is now composed of copper-plated zinc. Copper-plated cents cost less to manufacture, and at 2.5 grams each, they weigh about 20% less than the older cent, which was 95 percent copper and 5 percent zinc.

Corrosion is the result of metal oxidizing. When metal comes in touch with air, the water vapor and oxygen content of the atmosphere react with the metal to cause rusting/corrosion. \n\nIf you were to cover the metal with a non-water based paint, like in automobiles, this process is then reduced, in fact it is stopped for sometime -till the time the paint and its base coats remain intact.

Start with no pennies:\n1 quarter\n2 dimes, 1 nickel\n1 dime, 3 nickels\n5 nickels\n\nNow try 5 pennies:\n2 dimes, 5 pennies\n1 dimes, 2 nickels, 5 pennies\n4 nickels, 5 pennies\n\nNow try 10 pennies\n1 dime, 1 nickel, 10 pennies\n3 nickels, 10 pennies\n\nThen 15 pennies\n1 dime, 15 pennies\n2 nickels, 15 pennies\n\nAnd 20 pennies:\n1 nickel, 20 pennies\n\nFinally:\n25 pennies

Like a penny with a hole in it.

Salt water. We use to clean rust off metal using kool-aid type mix because of the acid in it. Eats the rust away.
