Step 1: Tools & Materials

Only  One Tool Is Needed

This tool is your trusty computer,   which is necessary to buy the two NIB magnets.
I recommend you get ten of everything.............  your friends will love it.
And if your as old as the coin as I am get 20 of each.


Materials Needed

First you need a clean 1943 iron penny.  This is available through a numismatist ( coin ) shop. 
  1. I used to buy the iron pennies from Wonder Magnet.
  2. More recently I would buy 50 at a time about 40¢ each last year from a local coin shop.

You need one NdFeB Neodymium-iron-boron Disc Magnet, 3/8 in. x 1/8 in.
  1. Available from Forcefield Magnet

And you need one NdFeB Neodymium-iron-boron Disc Magnet, 3/8 in. x 1/16 in.
  1. Also available from Forcefield Magnet.

Step 2: What Is An Iron Penny

An Iron penny is basically made of.........Zinc coated Steel.
it  can  and does  Rust,
but the color is Blue like steel pic_1.
it is Magnetic and is strongly attracted to magnets.


Some Stats ;

The penny was made by the US in 1943, because of the  War effort that needed the Copper for bullets.
Real 95% Copper pennies circa 1960 weigh o.11 ounces,  while Iron pennies weigh o.10 ounce each. 
Keep in mind there has been  No significant Copper  in  American pennies since the 1983.
Present coinage is 2.5% Copper 97.5% Zinc per penny, circa 2000 weigh only o.09 ounces today.

See the four Iron pennies attached to a small stack of 3/8" diameter horizontal magnets.

And the five iron pennies step-stacked with a sixth vertical iron penny held in position by  NIB  magnets.

In the spirit of your iron penny @ burning man........ I gave mine all away! Since, I have purchased some and its a very addictive activity. Anyone who spots it or asks about my "hat pin" gets one. Thanks again
iceng (author)  onrust2 years ago
I was all set to buy another hand out set of magnets an coins for this years burn
when they whacked the tickets for this year :-(

Now the best are not going, sad...

onrust iceng2 years ago
Whacked the tickets?
iceng (author)  onrust2 years ago
Unlike all years before, they random selected who could buy 2 tickets
this year, because they ran out of the desert authorities 50K limit..

Ex ample, The people who spend $40,000 to put up a free bar only got
half their workers ( impossible situation ) so they are not doing the bar.

This hurt every art project.... In the 11Hour the desert authorities relented
to permit 60K tickets Too Late for restarting major art projects. 
Several mini burn events already occur ed on Indian controlled land.

The whole event is whacked #¬þ

onrust iceng2 years ago
That's sad. Seriously sad.......BUT, how have the "Burning White Guy" events been going :)
BLUEBLOBS22 years ago
I have lots of these. They are a cheap and easy way to start a coin collection. Very nice 'Ible.
-BLUEBLOBS2
iceng (author)  BLUEBLOBS22 years ago
Yea, saw your page.  You do good stuff with monies.
I enjoy using UV to see the hidden fluorescent reflector strip in US paper.

I think what made this ible soar was the word LUCKY ,
and it didn't hurt to have one of my pictures placed as the first Pic
in Google's images for " Iron Penny "

Thanks for commenting.   BTW publicize your next ible on Facebook etc.

A
Do you think any of my 'Ibles are worthy of being featured?
onrust2 years ago
So, did they use the same dies to stamp the iron as they did the copper?
Goodhart onrust2 years ago
not very many copper ones were stamped that year, In fact, IIRC, they are worth a LOT if you have one.
iceng (author)  Goodhart2 years ago
I can attest to that rarity having spent four score years searching for a
copper 1943 penny and never found such a coin.

A
Wow, you truly do learn something new everyday... I had to look up the facts on this "rare copper penny" and found some info that suggest an authentic 1943, copper U.S. Penny is worth $10,000 +

That being said, there are a lot of forgeries out there. Its considered an "error coin", because the U.S. Mint accidentally used the wrong planchet metal, but coins got out before the error was discovered.

I must be checking my coins more often.... even here in Canada, our coins are inundated with U.S. pennies.
iceng (author)  canucksgirl2 years ago
Very true, But the iron pennies cost only 50¢ US

A
Goodhart iceng2 years ago
I think I read somewhere that only a few hundred may have been struck, and that most of them are in the hands of collectors....with maybe 6 or so in circulation if they haven't been destroyed somehow...
iceng (author)  Goodhart2 years ago
My research also confirms 6 are still unaccounted.  Good luck finding one.
I have often thought about using two simple servos to position pennies
to a viewable neural net algorithm which can reject improbable copper dates from my kilos of old copper.

A
Goodhart iceng2 years ago
There you go, with all that copper, you may very well hold a few of them :-)
iceng (author)  onrust2 years ago
No idea.
Maybe a numismatist will chime in.
onrust2 years ago
I just had one in my hand! The girl at circle K had an odd penny that would not go through the machine. That's a heavy little sucker! It really is something to see.
iceng (author)  onrust2 years ago
Yea..... They do grow on you, I forget my iPhone more then the coin :-)
onrust iceng2 years ago
OUCH!.....bigger magnet? lol
onrust2 years ago
I had no clue there was an iron penny. I just seek the wheat!
They're actually Steel, not iron.
iceng (author)  imbignate2 years ago
You are correct and "Steel is an alloy that consists mostly of iron and has
a carbon content between 0.2% and 2.1% by weight".

I have many Rust ridden pennies and no gentle way to clean the rust without
defacing the coin.
When thinking of steel the concept of stainless and poor magnetic properties
come to mind, however neither of these steel distinguishing characteristics
are presented in my favorite penny.
Based on this, I will continue to refer to this coin as an Iron penny :-)
Please tell me, what do you think now ??

Bard iceng2 years ago
Have you tried using phosphoric acid to remove the rust?
iceng (author)  Bard2 years ago
No I have not.
Is it available over a counter ?
How concentrated would you suggest ?
And thanks for speaking up.

A
Bard iceng2 years ago
I'm not sure, I know my grandpa used it to remove rust on farm equipment.
Bard Bard2 years ago
I looked it up and other names for it is rust converter, and navel jelly. if you want to search online. It turns the rust black and according to some sites it can be scrubbed off. I recommend testing it first on something expendable to see how hard it is to remove the black oxidation.
iceng (author)  Bard2 years ago
Thanks for the extra work I will be trying it after I return from the Burn,

A
caarntedd iceng2 years ago
Don't use phosphoric acid to remove rust from anything precious. Also it is nasty dangerous stuff. Use molasses. It is safe and won't remove any material other than the rust.
iceng (author)  caarntedd2 years ago
Right... I have learned it's power staining silicon to measure diffusion depth.
And then one day found a hole through my red tie before lunch !

A
Thoth iceng2 years ago
Steel is not necessarily stainless. Stainless steel is a particular steel alloy containing chromium and nickle in addition to iron and carbon, which also accounts for its poor magnetic properties.

There are dozens of steel alloys that will rust as easily as iron and have equal or slightly improved magnetic properties. Though you are free to call your pennies what ever you desire.

A cheap source of phosphoric acid is give the coins an overnight soak in diet coke. Or another method is place them in a jar with distilled vinegar and salt (doesn't matter really how much) and give it a shake.
onrust iceng2 years ago
I think ferrous pennies are cool. :)
iceng (author)  onrust2 years ago
Thanks onrust, Ferrous is cool :-)

A
imbignate iceng2 years ago
I say you can call them whatever you want, but they will be known forever by numismatists, the department of the treasury, and the US Mint as Steelies.

Feel free to note in the link where it says:

Composition 100% steel with a thin layer of zinc

As I said, feel free to call them whatever you like.  The one in your post looks like a Doug.  Doug the penny.
iceng (author)  onrust2 years ago
Neither did I and never found the 43 penny until
a kindly coin shop told me about it.

A
During the war there was a high demand for copper by military arms manufacturers, so they switched the pennies from pure copper to steel, since steel was more abundant at the time. Naturally, pennies have to cost less than a penny's worth of the material their made of.

Also, 50 pennies for 40 cents? Good deal.
iceng (author)  mattthegamer4632 years ago
Yea, Fifty pennies for 40¢ each comes to $ 20.oo over a year ago.

A
I should have assumed. Anyway, cool stuff.
mrfixitrick2 years ago
This cool idea will also work fine with most Canadian coins. About 1/3 of Canadian pennies are steel and are magnetic, and all of the other coin denominations are too. The Euro is also magnetic.
iceng (author)  mrfixitrick2 years ago
Wow.... I do enjoy ibles all ways learning. I bet Canadian Steel coins don't Rust :-)

Thanks for the info M.

and steel is an alloy that consists mostly of ferrous iron.
