when they whacked the tickets for this year :-(
Now the best are not going, sad...
A
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

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.

copper 1943 penny and never found such a coin.

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.
A
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
Maybe a numismatist will chime in.
Thanks for the info M.
and steel is an alloy that consists mostly of ferrous iron.

I got into a bit of a heated argument about "Iron coins"
and I agreed not to call American or Canadian coinage by the "I" word.
Now, I can only call Euro coins as Iron.
As you know Fe is attracted to magnets.
A
As DabeAltis took me on.
Yea........ Canadian pennies Do Rust as well as the 1943 US pennies do,
but I hope not for a while at where I'm going to be tomorrow
What you have described is called "cast iron" and has more than 4 percent carbon in solid solution with iron.
Iron (or pure iron) has almost zero carbon in solution and is very ductile and soft.
A piece of iron the size and shape of a penny could be bent in half just like you describe a "steel penny" can be.
A piece of cast iron the size and shape of a penny would just snap and not bend at all.
Steel has less than 4 percent carbon and falls between iron and cast iron in it's properties.
Please understand I have listened to the reason of many others before you
on this kind of Ferrous penny being in reality a Steel penny with a zinc flash.
I also agree the Canadian coins are also steel.
That just leaves the Iron Euro :-)
A
Canadian pennies made in 1996 or before are 98% copper, .5% tin and 1.5% zinc.
US pennies before 1982 are mostly copper, but after 1982 became copper-clad zinc.
"Steel is an alloy that consists mostly of iron and has a carbon content between
0.2% and 2.1% by weight"
I like graphite it's as bad as silicone thermal grease ( white shaving creme )
on cleaning up. You are very correct by volume carbon is a bunch.
Thanks for reminding me what carbon did to the Japanese feudal sword !
After eliminating this continent all I have left is the iron Euro LoL :-D
Thanks for the fun.

I'm impressed by being the first and right now only ible to get a comment
from HaandYAndy and thanks for the memory Sir.
I guess we like call it what we learned first. I did watch a program on the 43
where they reported less then forty of the 43 copper pennies were struck and
only eleven were accounted for at this time.

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 ?? . . . . . A
Thank you, for the compliment.
Also read your comments enough to see you are not averse to having fun :)
I apologize if some feel I pushed the issue too hard.
A
I fully accept yours and several others well intentioned guidance.
It is Steel because of a little carbon :-)
And yes 1943 steel pennies were coated with zinc, possibly accounting
for the color in my pics.
Stainless is different then steel.
Did you talk with your numismatists and find out there are some
IronSteel pennies made in the year before and after 1943 which are
worth more then pocket change. Including a just a few 1943 copper pennies.

I've seen more than a few mistakes, and remember that the vast majority of legitamate colleges and universities wil fail you if you use wiki-poopie as a source.
Newspapers aren't that much better in my experience. I have to give you an
apology for a guilty use of wiki in this ible with several metal definitions.
Not to harp, but years ago when I learned my birth coincided with the 43 penny
I was elated. Here is a ferrous coin strongly attracted to NIB magnets that
I hand out at Burning Man and I can write an ible about it.
What Great FUN ! !
Rather then some one me who was born the year the penny was minted ?
Have you ever wondered why the military was depending on GPS for war
activity in the early years of the satellite deployment ?
An opposing nation could send up a simple rocket to get near each
GPS satellite and detonate 99 ball bearings to knock it out.
A few ball bearings will destroy any fragile GPS satellite stranding any military that is GPS dependent in a war event, Huh ?
Well they, our geeks put radiation hardened satellites into that Van Allen
Radiation Belt and since the US was the only major power with rad hard
electronics any one trying to make an electronic package that could find
and navigate close enough to a radiation shrouded satellite didn't stand
a chance of electronics surviving long enough to do any damage TA DA..
Now you know why certain electronics cannot be shipped out of country !
A
However, by inducing electric current on wires it's possible to cause some issues... specially if the magnet is big and is near the wire.
Magnetic band cards are obviously easily affected, same for magnetic tapes, or VHS tapes.
Destroying an hardrive would require quite powerful magnets to be held near it, they are shielded against electromagnetic interference, and the magnets inside them are powerful enough to attract each with an hand in the middle (they can even hurt you if you let them 'grab' a piece of skin).
Another thing... don't let magnets stay near a compass... they can magnetize the outside box rendering the compass useless.
You can solder magnets, but not weld them, obviously overheating them is never good, their metal coatings are usually hard to solder though.
In any case is better safe than sorry... magnets can induce current on wires, magnetize or demagnetize stuff so don't risk it and play safe.
Guess I was traumatized when the iPod got killed in my pocket so long ago.
Old terrors make you over cautious LoL.
Thanks for staying on top of my ible :)

They can be machined with an abrasive bit (microgrinding through it to avoid fractures). The most common type available to a hobbyist is probably diamond embedded nickel dremel (rotary) tool bits.
They can be soldered - many RC racing enthusiasts solder these to wires to create their own custom battery charging harnesses, though it is true you have to avoid overheating them - regular 60/40 solder melting point is below the destructive temperature of neo magnets, though you should probably opt for lead free solder if it will be in continual contact with skin as when integrating them into jewelry.
They will not destroy a hard drive, and are very unlikely to wipe your credit cards. They simply aren't THAT powerful. In fact, hard drives have one or two significantly larger neo magnets in them.
Used to carry a 3/8" dia NIB in my pocket Where it met my iPod six years ago.
!!!! ToTaL HD Death??? !!!! I'm telling you True here.
......................Please Don't Try It.......................
The Apple Store gave me a two digit discount on a new iPod.
But it will most certainly wipe your credit card and render useless.. Don't believe me, go ahead and try. if you dare...
I'll take your dare though! I won't do it to my credit card but I will do it to a debit card (looks just like a credit card) I received as a rebate payment and it has no monetary value anymore. Tonight I will take one of the significantly larger neo magnets from a hard drive, wipe it back and forth across the magnetic strip about 20 times, then take it to the gas station I'll be stopping at and see if they can read it.
I'll post the results in a new reply here.
On another note, I remember hearing someplace that neo magnets contain cancer causing compounds and it's not recommended to cut or grind them without proper precautions....
What field strength is needed to do it, is an experiment beyond my willingness to find but certainly direct swipes with a roughly 10 gram neo magnet will corrupt a magnetic card reader. As a scientifically minded person, I can't assume more or less than that, only that I was wrong and the range was wrong in how much magnetism it would take.

The near first microprocessor I know of was a 4bit machine (4004).
then came the 8bit machines ( 8008 ) followed by the ( 8080 )
where I got involved.
Next came the Z80 produced by Zillog and the RCA Cosmac1802
which was a CMOS 4bit, 8bit and 16bit machine that went into space
because CMOS can survive the Van Allen radiation belt exposure.
The first electronics in space were Wire Wrapped circuit boards because
they could survive the launch vibration better then a PCB those days.
Hope you didn't mind my bending your ear.

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.
Is it available over a counter ?
How concentrated would you suggest ?
And thanks for speaking up.

And then one day found a hole through my red tie before lunch !

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.
A
a kindly coin shop told me about it.
A
Also, 50 pennies for 40 cents? Good deal.
A
Sorry my daughter sold hers days ago.
gluing the steel penny to an ordinary button? Or gluing/screwing the
pennies a tie tack or cuff links?
But, it's an interesting concept, and your instructable is a nice introduction
to NIB magnets. I'd like to see more from you on the use of these magnets,
as in table-tops games maybe.
A
moves.
One magnet will work until you slide the penny off to show and then the magnet falls down where you may not want it to look for it :-)
