This is a hard one to explain. Starting easy at the middle of the coin a die crack or the start of a Lamination. Here are the overall images first:  At the top on the dome it appears to be lifting from the right side, but lower down, it shifted and seems to lift from the left. two pictures of this one with lighting from over head and the second from the left:  Next 3are of a shallow lamination that reaches and goes over the edge of the coin (For now - ignore the huge gouge):   Now the other thing that has me scratching my head. The gouge - it looks like a hit but this is an uncirculated coin. the gouge or hole seems to have 2 die cracks inside it. the does not seem to have any movement out and away from the center of the coin as it does not protrude beyond the perimeter of he edge of the coin. I outlined the circular edge of the coin to show this. Also, the edge is not bulged out as would be expected if it took a downward hit, nor is there any damage to the obverse just under the gouge on the reverse.

I suspect what you have labeled "die cracks inside gap" might be the edges of layers of the lamination, whether all the anomalies are lam related is tough to say, interesting coin though

On this you can see the de-lamination (exfoliation) of the material on the left of Monticello. The rim show that during the milling a part of the material dettached and the right of Monticello a big Die Crack. My opinion on this. On the side I see the profounder of the crystalline separation of the material.

Adding my opinion that it all looks like delamination which is readily seen in the War Nickel series. Especially the lamination on edge which has not yet peeled off. Great photos indeed - they really show what is going on and make it so much more positive to offer informed opinions. edit for spllgening

WOW, Cool - not one PMD in the 'opinion lot'!  This is a great day. thanks all. Just curious though, did the blue arc showing off the edge of the rim come in handy? (that was a pain to get right)

I could tell the coin was round due to the background, though instead of the arc a brighter background might have been more helpful, overall a very nice job with the pics

Rarely I see some such clear photos. No idea how you took, but look like back when I worked the medical photos was took.

Silvio, I have a Tomlov scope for the close-ups, and just my cell phone for full coin images.: I connect the scope to my PC and save them directly to the PC from the scope

All the imperfections on the left side appear to be the result of delaminating metal. The thin line on the right may be a die crack or a lamination crack -- I can't tell from the photos. If it is a die crack, it's obviously unrelated to the defects on the left side.

I think the line in the middle may be a lamination - it seems to lift up in 2 different directions. I'll post up better images tomorrow when I have better lighting.
