1879 Penny metal above lighthouse

[DrLarry]

I have been studying the bronze series for a few years under the microscope and would ask if anyone else has one of the the following in their collection:

1879 REV J penny large metal addition above the lighthouse.

No sign of compression or metal distortion. Additional observation in subsequent examples of the 1879 penny show a raised mound and removal scars matching the form of the metal found on specimen A.  The metal is at its highest 1 mm off the surface rises in the middle. defined edge and coincidentally seems to match reverse H lighthouse top. It is an intriguing metal addition and I would ask if anyone has any evidence in 1879 pennies of anything similar. In 3D visualisation of the anomaly there is no strike to any of the metal in the vicinity which could cause a ripple in the metal. Note that the metals medial apex would shift anything slightly to the left of the present light house REV J all other features so far remain the same for this die type, although I have to look in more detail.

well done ...see the purpose of forum is to share to aid us towards better understanding.  Is the shape the exact same one ? I would be interested to see an image of it and the N of one on the same coin ...Thank you so much for replying

Auction 152 lot 2434 has the pics.

yes it is exactly the same in every way ...what does it mean this is the question.  I do love novelty in it so many answers lay 

[DrLarry]

you always are so helpful many thanks

Oh the interesting thing is than in other 79's there is a section which is raised as a mound and the scars of removal are clear and the scars correspond to the same shape.  It suggests that the die has been ground down to remove this small shuttle.  how did you rationalise its presence because presumably it results on a gouge in the die.  Is this then accident or purpose.  It is uncanny the resemblance to the tops of the thin light houses ( I stray into dangerous territory here LOL)
