At around 1 and 7 o'clock, the rim looks flattened. In that same area, the devices appear to be grease-filled. I would have thought PMD but the grease-filled appearance of the devices nearby is too coincidental for me to conclude it as a PMD. Is this just struck through a grease-filled die all along the rim and devices? But, weren't the rims formed prior to the strike back in 1909? It's like a reverse cud on the rim - like a mint error indent. Or, what error is it on the rim? Thanks in advance!
Interesting.. Somethings come to mind Tapered Planchet - One side is thicker than the other High Pressure Strike - Raised rim due to a high pressure strike on to slightly misaligned dies This is just my opinion.
That's a good question. I have a few 09 Lincolns, some of them have this type of irregularity. But, yours seems pretty severe.
Hypothetically speaking, if something like hardened gum (or hardened greasy gunk?) got sandwiched on the respective areas, wouldn't it distort the rim and fill into the devices of the die? Then, a grease-filled appearance would come about on the rim as the press sandwiches the gum against the die and collar. If the planchet was malleable enough and not heat treated to its final hardness, then maybe the rim would have been soft enough to receive a flattened impression.
I'm torn between you and paddy. Both great guesses, but not what i was thinking. I'll give paddy the 1 up. Cuz
First off not a strike thru. The other side of that area is the bottem of the bust and the MOST SEVERE difference in height from top of device to field level so just failure to fill from weak strike IMO the damage is from being roll pinched between conveying components probably. But it looks like it’s been pinched or rolled to me. Before I retired were I worked I maintained about 1 1/2 miles of conveyor system among other things. I’ve seen washers turn up on the floor that look like that! Reed Looked again and found it. Pinch marks on the device! At least that what I see but it’s been awhile since I’ve had new glasses
I wish I could say but the image is inconclusive. But it does appear to be post striking damage. At some time after the coin was struck it received the damage we see today. @David Setree Rare Coins called it in post #6 and I agree with him some how this coin got pinched. Hope this helps, Reed.
On the obverse rim at 7 o'clock, it looks like it's either clipped or it took a direct hit or shear at roughly 45 degrees from the flat of the rim. That's what's nearly directly behind that "grease-filled" like reverse.
