1948 Lincoln Error, "Fat Coin"

I have had this coin for a few years now, at least, but I never really understood what happened to create this error. The best I can come up with is that the wrong blank was used, maybe a copper blank from a larger foreign coin since the US didn't have any other copper coins in 1948 that I know of. Would be interested in any of your thoughts on this error. Also was it worth the $600 I paid for it? Just kidding, I think I paid $10 or $15 for it.

I am not sure what I am looking at, I can't see how This coin could have been chambered, I believe it is in a bezel.

 

It looks like a post-mint altercation. Somebody used a hydraulic press to push the coin into the brass circle. You can see the pressure point on the inside of the pennies rim on the obverse.

 

I agree. That Cent is inside some type of strange Bezel. That is not a larger planchet.
@Electron John .. Think of it this way.
A larger blank planchet would not fit into the chamber that holds a blank Cent Planchet. So that rules that thought out.

 

I think the bezel theory is a good one. I will check to see if the outer bezel material is the same as the coin.

 

Why? I don't see why it matters if the outer material is the same as the coin. It could be a bezel made from another penny... it could be made from scrap copper. but it's pretty clearly not one continuous flow of metal (evident by the line where they connect).

 

Because he can! He works in a fancy lab with special electron microscopes and metal analysis machines. I would also!
Look at his avatar..amazing images

 

If they are different materials then that proves that. If the same material, extremely unlikely when one considers all the different alloy mixes out there, then there will still be some question. Who goes out of their way to create a bezel of the exact same alloy as the coin they will press into it?
Plus I am 99.9% sure Pickin and Grinn, any everyone else, is correct about it being a bezel. Nothing else made sense to me which is why I posted it here.

 

And as paddyman98 said I can test it easily enough in my lab. It is pumping down in one of my scanning electron microscope right now.

 

lol, ok that makes more sense. I was missing some information there and couldn't understand how it would be economical to test ;P.
I'm just telling you what I see. I worked in a machine shop and have extensive experience with visual inspections of small parts. I would guess that the outer ring is another penny made by similar fashion as coin rings- by punching a hole in the middle and then expanding outward with a stretcher. There is a pretty obvious ring on the inside obverse of the penny from the pressure, and the outside ring is flattened on the reverse.

 

The bezel is pure copper (as close as my EDS detector can tell anyway) and the penny is brass (~96% Cu, 4% Zn) which is about 1% off for what it should be (95/5) but I only hit one point for a few seconds. So it is a bezel. I hope I am wrong about how much I paid for it.

 

The physical impossibility of a Mint process to create something like that should be factored.

 

Why is it impossible to strike a penny on a large blank but possible to strike a dime on a nickel?

That is a broadstruck dime mounted on a nickel to photographically show the Dime's increase in size. Read the writeup.

 

You are right. That was a deceptive picture.

 

Yeah, it was.

 

That is a cool piece! Ida bought it.

 

The seller stated that their Dime is a Cent ... Nice Broadstrike though

 

It's a simple rule. Just like I metioned before. Just go down the ladder
A quarter blank will not fit into a nickel, cent or dime chamber
A nickel blank will not fit into a cent or dime chamber
A cent blank will not fit into a dime chamber

If you ever do see a smaller denomination such as a nickel on a larger planchet, most likely it was Mint Employee assisted. Fake error!
Such as this
(Not my NGC slab)

 

Yes, as I understand if you take the collar off you can fit any size coin under any denomination press. But that would have to be done on purpose. Are you saying errors done on purpose are less valuable because they were not an accident?
