Interesting coin. Here my worked photo:  1. The green circle show characteristic end of a delamination. 2. The red circle put me a question due to the kernelled sign. Those are parallels and seem to be something kernelled roll pass trough. 3. the blue line show raised border of the kernelled signs. 4. the square I can' t pronounce . My opinion. Nice and interesting coin. |

Thank you silviosi for your assessment,the square piece has the same width as the wide part of the delam area and all seem to be one piece but folded over during the strike and then has fallen off
, although we are assessing this from the photos, in hand is more pronounced.

@ Chase007. Having the coin in the hand is the best. This it is the reason that some of TPG I work with them has to pay 2$ more because the photos so not show me exact structure. In my opinion is a nice delamination coin, why because majority are PS Delam, your is Pre strike delam in my opinion. |

But the lamination is not missing. It is attached and pushed to the left of the design. That is what you are seeing on the left part of that area. It is flattened against the bust.

The lamination looks like it was pealed off to the southwest for a bit, then folded back up towards the North by Northeast before being pressed back down onto the device.
I think the coin took a hit way back in the day by an object starting at the rim at the 2 O'clock position then traveling across the coin to the 8 O'clock region. At some point the object freed itself from the lamination and skipped over the field and hit the rim upon exit at that 8 O'clock rim area.

I agree, could happened, like a rebound on press. Coop has a good right point and also Dearborn and I am glad because confirm my theorem of a delam before striking. Those delams are very thin, so a 60 ton force strike and they moved before for one reason or other will make them fusion with the mass (theoretically).

I think silviosi's initial assessment and Dearborn's are more in line of what has taken place , I maybe wrong but the area below the raised edge to the North and through the lower Two Third portion of the square area looks like a break off and a separation, and in the upper Third portion of the square area looks part of the Lam still remaining. Just as my other Lam example below ,if any portion of the Lam were to brake off and separate from the planchet the remaining raised edge on that area would look similar to the North edge of this Lam.  |

Thank Chase007 for your photo. I will keep for example. You has in this coin two kind of delam. First due to rolling and second due to striking. Sound strange for years of classify simple delam. I agree, but what is happened?, First delam is rolling at 100% the symptoms are there. Rolling always one side has the tendency to be strait due to the molecular structure. In the green circle you see the end of the rolling delam. In the red circle is the strike delam due to miss of reheat the roll adequate, so the molecular structure do not rearrange. I work make the TPG to recognize the two different kind of delam. the second me I name cracking planchet delam. for the numismatic community those errors are less valuable errors then die gravure errors or moving strike dies, when in fact those are very rare, Could happened on 10 to 20 coins by roll comparative with dies errors on thousands. Market mystery.  |

Out of curiosity what is the weight of the 1948 cent?
I'm asking because, IMHO, that looks more like it is struck through a retained copper strip/foil. It is not linear like most laminations. The extra copper might have been too small to affect the weight enough so it might still be within mint tolerances.
Words of encouragement are one of the major food groups.
We need to consume them regularly to thrive and grow.

It should be normal. All the laminated area is still on the coin. Just moved to the left.

1948 was suppose to be 95 Cu and 5 Zinc and Tin for 3.11. After the war? the production of alloy? If is 96 or 97 Cu will be heavier a little bit then 3.11. Mint tolerances for that time? Who know? Seem to be normal for me.
