I don't see this listed anywhere but it certainty looks extra thick to me. It even has a floating roof!! What do you think?
@Scubalou …if this is out of that same ‘69-S roll, here are some more tips to use. The ear and cheek have that flattening. I warned you that .you would find more on a previous post. But for this one I wanted to point out this thickness you reported. It is the result of a weakened strike coupled with circulation wear, imo. When the striking pressure is less, the relief of the devices (hair, letters, numerals) do not form completely. And the darkening of the coin in spots is where fingers touched the surface while circulating. This info will help you as you go through all those cigar box rolls. I am optimistic for you, even envious, that you have a great supply to go through. I am confident that you will find some great coins and look forward to you sharing with us …imo…Spark
Thank you. That makes more sense than the DDD others have said. The devices are not mushy so low pressure makes more sense. I understand the darkening and flattening - should have stored them laying down, too late now. I'm about to post another one with a strange RPM. I say RPM because I can see a broad line in the middle of the S. Thanks again. Lou
Yes, that is a floating roof. It is caused when the die is overpolished, trying to get more life out of a deteriorating die.
Yikes!! In my haste to get through an entire roll of 1970 S Lincolns I tossed it back. You however are right, I didn't check the FG, probably wasn't a true floating roof. I was just trying to make up for the last one. lol
You would be suprised That had the right amount of die deterioration to be a no FS. Let me see if I can find a 71D in an odd die stage.
OK, Maybe we can start with the shiny area above the roof line it runs under UNUM and wraps the side of the parapet wall. What caused this? There are clues in the photo. Is there die deterioration, or is it die abrasion? Was it there when the die was fresh or was it mint assisted. Maybe it is part of the die clash that happened to the majority of the bag. I have pulled a few Counter Clashes. Maybe just maybe it is all abrasion doubling. Here is the obverse.
Way above my pay grade, but the area below the memorial seems spotty and cratered. Since this is copper could it be a planchet error? Possibly some corrosive over spray?
Thats a good question, there is a ghostly look to the coin as in PIDT. https://www.error-ref.com/?s=Progressive+indirect+die+transfer
I wouldn't call the image so much as "ghostly" since it is too low to be an outline of Abe's head and inconsistent with his shape. It does not conform to the shape of any of the obverse devices. Therefore I have my doubts about PIDT. It's random inconsistency defies a production consistence with that of striking error. To me it's more like a "sunrise" behind the memorial randomly spreading down the sides to "ONE CENT". The "sunrise" also appears on the obverse in front of Abe's face - fading into "trust". Possibly also behind his bust appearing above liberty. None of these signs point me to a design transfer. Personally I'm leaning to planchet irregularity, especially since they are different on the obverse and reverse. IMO. BTY It's unfair to force my brain to function in this manner so early in the morning, after only one cup of coffee. Do you grad on a scale??? Sometime I'd like to discuss "die deterioration", seems to be a standard answer somewhat like "struck thru grease". Especially when applied to only some devices. Seems to me it should be more consistent throughout a die. Thanks: Lou
I think you answered your own question. It looks wider and the roof is floating. What makes the roof float? The die has been polished. Why did the mint polish the die? To remove some of the wear. So your coin looks the way it does because the die is worn and should be replaced.
I tried to dull down the luster. These are fresh out of a $50 bag. I tossed a few that were worse off than this one. If you look closely you can see the back of lincolns jacket running up thru the left side of the memorial bays. And from the roof you can see the back of the jacket running towards the rim between ED of united. Also a weak outline of the front of Abes jacket from roof to AM of America. If you look closely at the area, I first referred to it is still there but not as flashy in this photo. The area is tapered from the roof to field and has a completely different look than the surrounding luster. What you are seeing is an early form of ghosting PIDT or die deterioration. This is what the mint was trying to get rid of when they polished off the details of the upper roof. And made a floating roof variety.
