1964 silver chrome penny

5 years back my father found a 1964 penny which seemed to be silver or chrome or sumthing of that nature underneath the escalators outside of the congress building when he was rebuilding them. any info on this coin wuld be greatly appreciated. also the coin weighs 3.3 grams and is magnetic

A picture would help.

I know not of any official coinage like the one you are describing. Perhaps a kid had some fun with some spraypaint?

 

Is it strongly attracted to a magnet jumps to the magnet) or weakly attracted 9you can tell there is an attraction, or a strong magnet barely will lift the coin.) i'm betting the attraction is weak and that is because the coin has a nickel plating.

 

Sounds like it could've been dipped in Steel or some other metal that is attracted to magnets...

Plated, post mint damage.

 

My bet would be plated. But you could always take it to a coin dealer and get his/her opinion, on the really really off chance that it's something exceedingly rare. Never hurts to take a look.

 

I don't think so. To dip a something in steel the steel would have to be liquid, i.e., melted. The melting point of steel is around 2600 degrees F and the melting point of a bronze cent is somewhere around 1800 degrees F. If you dipped a bronze cent in molten steel the coin would quickly melt.

 

It could be many different many metals. Off the top of my head I know tin is magnetic and melts at about 500 F.

 

Tin is NOT magnetic. The only three common metals that are magnetic are iron, nickel, and cobalt. There are also various alloys that are magnetic.

 

D) final answer (why not, I mean Lincoln did wear a top hat!!!) ))

 

Yeah I remembered that when it wasn't 4 in the morning. Sorry, but it does have a low melting point.
On a side note I was talking to my brother who was a chemistry major and part-times in a chem lab and he said that there is some process where you could get the steel to be slushy at around 1800-2000 F. And also, when the steel coats the coin it would take a higher temp to melt because the energy has to transfer through the steel into the copper.

 

Copper and brass can be chrome plated.

 

Chrome plating isn't magnetic, unless it has been chrome plated over a nickel plating. They often do that because the nickel adheres better the underlying material and the chrome adheres well to the nickel.

 

I read that at least three times before I saw the second "s".

Maybe I should back away from the keyboard for a bit.

 

I also have a 1964 silver colored penny. It weighs 2.9 grams. And pulls to magnet as much as my 1942 quarter.

 

This thread is from 2011. Can you please repost by starting a new thread? You will get much better and more responses.

 

A magnet shouldn't pull a quarter.
Iron, Nickel, Cobalt these are magnetic.
The quarter is 90% silver and 10% copper. Not magnetic at all.

Your penny could be plated with something that is magnetic.
It's not silver, or steel or aluminum. It's copper.

If it were minted on a foreign planchet that was a different metal,
the size and weight would be different, and if it has complete rims
like a regular penny, it is a regular penny that has been damaged by plating.

Exit necro thread theme music.

 

We played with mercury back 60 years ago from broke thermometers. [ before we learned it was poison.] we massaged mercury on a number to pennies back then Might have done so again about 25-30 years ago. I have about 4 ounces of it in a bottle some where. Kinda interesting to see a big steel ball-bearing float in the bottle

 

Sorry

 

Best to start a new thread and not hi jack one. You'll get more answers.
