Thanks again to everyone for adding their insight and thoughts.

.. when the metal become cold and accidentally cold air flow arrive, the surface will has all crazy forms of ringcols.
(I believe ringcols = wrinkles)

... Or also some carbonic debris (previous Zinc oxide) from the liquid metal and then after the rolling those debris will fall making space to such surface design.
Thank you for that info. I have no experience with what's possible while pouring molten metal but realize it's the beginning of a process to get the planchets.
The weakness on the obverse rim at K7-K9 leads me to think this may have been near the end of a roll (tapered?). Which is where a lot of planchet anomalies are found ragged clips, fissures,
Blowholes, etc.)

I would think that a strike through to this apparent depth would not transfer sush crisp letters as are seen in the bottom of the anomaly. ...
Thank you for saying that so clearly. I was having trouble finding the right words.
Quote:... I would imagine something softer than metal made these impressions in the reverse post strike. Think
Texas Cent on a smaller scale
Interesting thought and perspective.
Lincoln Shield cent specs (Numista)-
Weight 2.5 g
Diameter 19.05 mm
Thickness 1.55 mm
Specs on this coin-
Diameter-
E-W = 19.00 mm
N-S (at the hit)= 19.22 mm
East of hit (point of bust)= 19.01 mm
West of hit (VDB)= 19.09 mm
Thickness is 1.50 mm
Weight- 2.48 g
Usually we see plating blisters in the fields and they tend to expand upwards.
My thought is if there was a zinc blister/blowhole (in the zinc) just below the surface that collapsed after the coin was struck, the effects would be similar to this coin wouldn't they?
(Thanks for everyone's patience. I'm not trying to
but I am trying to understand this coin. I may have to try to reproduce this effect with the "
Texas Cent" technique.)
Words of encouragement are one of the major food groups.
We need to consume them regularly to thrive and grow.
