2009 LMC only 2.41.grams and showing Zinc

I not sure if this is an error but the 2009 should be 2.62 gram from what I have read, or just like the 1909VDB.but one of mine shows a zinc & is only 2.41 gram. here is the pictures

Did some research.. apparently they are still on the zincers... I thought they were changing the planchets compositions... but I don't keep up on the new stuff so much... If it is in a zinc planchet.. im thinking improper plating job... resulting in a thin copper layer

 

A normal copper-plated zinc cent weighs 2.5 grams. I don't know where you got the figure of 2.62 grams. A completely unplated cent would average around 2.45 grams. I suspect your cent was struck on a planchet punched out of stock that was rolled slightly thin.

 

Yesterday I had it check at Alabama Coin. we went read all the press & online info we could find on the 2009. and it said 95%copper & 5 % zinc.
but all the other in the roll are 2.63 this is only light one

 

Mike,

What do you make of the starburst pattern in the fields? Is that also a product of the thin planchet?

 

I'm confused too about the zinc, and copper cents. I thought all the regular business strike coins were going to be zinc plated copper. So how do we get the 95% copper ones?

 

That would be unrelated to both thin plating and a thin planchet. Nobody is quite sure what causes the starburst effect. You see it every so often on Sac and Presidential dollars.

 

Per the US mint http://usmint.gov/mint_programs/circulatingCoins/index.cfm?action=CircPenny

 

95% copper cents were last produced in 1982. Since the middle of 1982 cents have been composed of copper-plated zinc.

 

3.11 gram is in the red book for 1909VDB
2.63 is what the other coin in my roll were
and one 1 with zinc showing was 2.41
It is ether the wrong planchet or a thin planchet.

 

You might want to check the accuracy of your scale.

 

We did 2 times

 

Why would I lie????

I just post what I found in my roll.
I didn't want to start a war of words

 

Thanks Mike but I was referring to the 2009 Lincoln ( I should have said that) aren't some supposed to be made of 95% copper like the original 1909? Sorry to jump in on your thread Jello.

 

raider34 thats OK

Lately if anyone post a coin they are made out to be a fool!
And I don't fall in that category. I just report what I find

 

Could be a thin planchet Jello very much so I will go that route

Thin is what I was thinking jazz !

 

I didn't notice anyone doing that. What is happening is the ruling out all possiblities of what it may be. No one is attacking you, just the coin.

 

So you tested a reasonably large sample of recent (post-1982) cents and they came out to 2.5 grams (+/- .1g)?

 

I've consulted the US Mint's website and they will indeed make some special-issue cents of 95% copper alloy. Here's what it says:

"These coins will be issued for circulation in quantities to meet the demands of commerce. In addition, the Secretary of the Treasury shall mint and issue numismatic one-cent coins in 2009 with the exact metallic content as contained in the 1909 one-cent coin (95% copper, 5% tin and zinc). These numismatic versions will be included in the United States Mint’s annual product offerings."
