Die crack or planchette blister? 1 1

Understand what you're saying and I tried pushing down on it. It is raised up and solid. 100% raised out of the coin solid as a rock. So what you're saying if it was caused by gases and it was a blister it wouldn't be solid correct? 

Does this mean it is a die crack?

 

On a 1984 cent, it is virtually impossible to be anything but gas bubbles. Trust me.

Then I think either it's a die crack or a break in the thin cladding that induced corrosion below, which expands and pushes up the adjacent cladding.  You would need to look carefully for any break or scratch in the cladding with like a 40x loupe or a scope.

I think it's a cladding break or scratch with corrosion, even if that may be hard to see.  It appears a little too straight and wide, particularly in spots around the date and shoulder, compared to most die cracks on coins I have seen, even relatively prominent ones like the attached die crack.

   I've never heard of anyone trying to "pop" plating blisters, which, if successful, would result in a damaged coin. They are identified by their appearance, which, to my eyes, is distinctly different from die cracks. It's hard to tell for sure from photos, but I stand by my original answer that the obverse exhibits a linear plating blister and the reverse a small die crack.

Since it's solid and does not seem to be consistent with a die crack, I think it's a corrosion induced solid blister like the attached from error-ref.com, and not a linear plating blister which would be hollow.  At least with how those terms are used on error-ref.com which makes a distinction between the two based on if the blister is solid or hollow.

Error-Ref.com Plating Defects:

"Plating blisters are hollow. They look similar to, but should not be confused with, solid blisters pushed up by subsurface corrosion."

There may be a snowballs chance that's a wide die crack being solid, even if it doesn't look like those I have seen.  Perhaps the coin was struck right before a die break and the significantly wider spots were edge spalling and widening of a crack leading up to the break.

That would take quite a lot of digging to find similar progressive cracks or cuds of the same coin with the die broken off where there is the line.  But I don’t really think so and it likely wouldn't be worth the effort, as even if a die crack that wouldn't add much value at all.

And a copper plated zinc 1984 (P) Lincoln cent with blisters has no added collector value in either case, regardless of any blister being poped either by checking it too forcefully or from the coin being in circulation.

Even a die crack is not considered to be valuable, just a neat thing to find .

For those scoffers, I have researched and found what seems to be an extensive source for Capped Bust half varieties.  This document describes the crack indicated above as a die crack.

Excuse me, but what does this have anything to do whatsoever with a modern Lincoln cent???

Oh boy, misattributing coins again.  The op's coin is a 1984 (P) Lincoln Cent!
