I'm wondering if those "tabs" at 5 and 11 o'clock protrude well above the rim of the coin elsewhere. Thx!

For what it's worth, I agree with makecents. The "compressed" metal has to go somewhere. Could it have been a 'defective" planchet?

That is a way cool and visually stunning error.
Take a look at my other hobby ... https://www.jk-dk.artToo many hobbies .... too much work .... not enough time. |

I agree with the comments here that this is an outstanding looking error.
Congrats!

So this recently posted Eisenhower dollar with a massive struck through managed to avoid any questions about the fundamental laws of physics but the OP's Lincoln get's questioned? https://goccf.com/t/477019FWIW, here's a PCGS graded Jeff with an almost identical appearance: https://www.pcgs.com/cert/35684604I think the more interesting question is how? If the webbing was retained wouldn't it have interfered with the plating process? The struck through area of the coin appears fully plated. Also, it's hard to see how it could have gone through the upset mill with the webbing attached either. I lean toward assisted error, but like almost all of those there's never really any way to know for sure and in the end it doesn't make it any less super cool. |

I have to agree with -makecents- on this one. This coin does not make sense at all. I guess we will have to wait until a 3rd party grader sorts this conundrum. Quote:So this recently posted Eisenhower dollar with a massive struck through managed to avoid any questions about the fundamental laws of physics but the OP's Lincoln get's questioned? So, I think some misunderstood what I was saying, I do not question that it is a legitimate error, it may be the best shield error I have seen. I was asking where the extra mass showed up, please read everything I said, in the order that I said it. I simply know that if it is the correct weight, which the OP said it was, then there has to be extra thickness or wider than a normal cent, which the OP said it was normal in those measurements too, this cannot be.... As for the assist, I would have to agree with this. Very nice error, gorham_collector!

To answer all questions or things talked about.
It seems mostly all struck thru webbings like the nickel someone posted all the webbings r bascially perfectly centered. That's just how it is don't know how but I don't think it was assisted as you'd have to stop the press place it on etc. highly unlikely. I feel it just happened the webbing was on the Planchet etc.and we can't explain how it happens.
Besides that part
The struck thru area was contained inside the collar when it was struck and Planchet perfectly centered in striking chamber so that's why we don't see any difference on the diameter.
The only difference is the tabs at the rim they slightly protrude up and also the font has the zinc and super slight flanging going on which comes with metal flow having to go somewhere when the copper has no where to go and flow.
Now the struck thru area would not show zinc or any stress bc the press and putting an extreme amount of force on the metal and pushing it into the coin just like any other struck big or small you won't see zinc if at all unless slightly Uncentered or boradstruck / off center.
The top left tab is super slightly raised a half a mm. And the bottom tab is not really raised at all.

. can you please add a picture of the coin edge-on to this thread? I'm wondering if those "tabs" at 5 and 11 o'clock protrude well above the rim of the coin elsewhere. Thx! Best I could do for a pic lol don't wanna take it outta the flip. But the tab 11 o'clock on the left in this pic u can see it ever so slightly protruding up and unevenness in the plastic of the flip is going up. The right side 5oclock is not even protruding soooo ever slightly it is. On the obverse pic u can see the zinc and sore slight flanging where the metal went bc of being restricted striking chamber and collar when struck .

Was that so hard? It would appear slightly out of round too, at the "tabs". That was all I was asking for....

Zinc Lincoln cents are processed differently than other coins, so direct comparisons to other denominations may require further discussion.
ARTAZN makes and rolls the zinc alloy, punches blanks from the sheets, rolls the blanks to Type 2 planchets, copper plates the planchets, anneals the plating, and delivers those planchets to the mints. The mints strike the delivered planchets without further pre-strike processing.
This coin has the copper plating in the area of the bowtie depression, including the edges of that depression. It appears that some of the plating is missing along the shoulders of the depression and the area around the edges of the depression. It's possible that the bowtie made it to the Philadelphia Mint, but the presence of copper plating in the depression suggests otherwise. That could suggest that whatever occurred may have happened during ARTAZN's processing, rather than at the Philadelphia Mint. Please note my emphasis on "could" and "may."
If the bowtie was present during plating and annealing, how is any of the copper plating intact in the bowtie depression? Conversely, if the bowtie was not present during plating and annealing, why is any portion of the plating disrupted in the depression? If the bowtie was present at striking, how is the coin's design fully struck immediately adjacent to the edges of the depression? Along that line, it would be interesting to see a high resolution closeup of the final "S" in STATES. If the bowtie was not intact at striking, how did the fins occur? If the bowtie broke off after striking, why are the inside edges of the fins smooth? The stressed area inside the rim at 3:00-6:00 on the obverse may suggest that the bowtie came off after striking. How? In addition, the recessed portion of the bow tie depression opposite this point on the obverse shows a relatively smooth surface. It might be interesting to see what ARTAZN's coinage team might say on this one.
Just some thoughts. Truly a fascinating coin!
EDIT: I'm increasingly leaning toward this being a genuine planchet error, with the damage to the planchet occurring at ARTAZN, rather than the Mint. I could see the bowtie attached to the blank after blanking, being rolled onto the top of the blank during the rolling into a Type 2 planchet, being pressed into the planchet and then torn off during the plating, and the edges of the tear being smoothed during the annealing. (The plating method is apparently a closely guarded ARTAZN trade secret.) The obverse stress could be the result of the striking process, which might explain the smooth insides of the fins. The missing plating could be explained by the coining process. This could explain the full strike to the edges of the depression. That's a lot of "coulds" here.
So much hangs on the appearance of the depression in the immediate area of the last "S" in STATES. I would very much love to see an angled view of that area showing the inside shoulder of the depression at and immediately below the "S."

Apologies if it appeared I was implying you had doubts about the legitimacy of the coin. I was not, but rather was simply expressing my sense irony over how the Eisenhower escaped this kind of scrutiny, even though the area of the indent on that coin is greater than almost the entire area of Lincoln Cent.

I can understand more clearly what your referring to and your explanation.
