This is a new one for me and have no idea what to call it. The "Y" in Liberty is very thin and on the reverse, the column is not straight.   |

I've never seen that either. The 1983 LMC is notorious for Struck Through Grease. Could that be what we are seeing here? |

Overpolished die with a die clash on the reverse. I cannot see it in the photos, but that's what you're describing. I really don't know why anyone would think thinner than normal letters would be the result of a Grease Filled Die. They are beveled...does it not make sense that if the field were raised that the letter would be thinner? This happens only in die polishing. |

Quote:I really don't know why anyone would think thinner than normal letters would be the result of a Grease Filled Die. I was making a suggestion based on the condition of many 1983 LMC. I wish everyone knew as much about the minting process as you. But, that would probably take all the fun out this for you. I'm happy my ignorance made you feel superior today. |

It's not a matter of superiority...the images show no evidence that the coin was Struck Through Grease, and we go through this in one thread or another just about every day. And believe me - this doesn't make it 'fun' for me in any way. In general the minting process and the things we find as evidence of that process on the coins is just common sense, really. That's all it is. Grease, or ANY viscous material sitting on a metal die is going to transfer to something the die is striking as a mottled, irregularly shaped blob that may or may not fill in the devices in the area depending on how much grease there is and how long it has been on the die. The difference between the result of a Grease Filled Die and the result of an overpolished die are as plain as night and day. 1983 is not 'norotious' for being Struck Through Grease - I have no idea where you heard that. 1983 cents are generally low in quality because the reverse master die was worn out and because the plating on the coins was often faulty...but that's all. Grease Filled Die strikes are just as common that year as with any other year. |

Common sense?  |

Not taking sides here scurry but sometimes if I'm completely off base and it's pointed out to me, I remember the lesson much better.
But I am puzzle about coppercoins not seeing the column...the curve right in the middle of the fourth seems pretty obvious...sometimes I wonder if we see different views on different computers.

ABSOLUTELY COMMON SENSE- If a person educates themselves on the minting process, they're familiar with the basic way that a coin is made. When one applies that knowledge to a coin they think is different, they will usually understand what happened. Once you've done that many times (with a foundation of understanding of the process), it simply is common sense.
Not that anyone is wrong for asking- not at all. But it's next to impossible to [correctly] answer a question without seeing the coin. Just like grading a coin over the phone!
Coppercoins IS an authroity- it's really not fair to lean on him for all of our answers, and then knock him or take it personally if we didn't "Guess" what the correct answer to the question in the post.
I think Maineman was more questioning the irregular shape of the memorial column, when I first saw it, before I read the post, it struck me as being an overpolished die. I've got some '95-P cents with a "fancy 5", looks like a whole different style, but it's just die polishing.
So, common cents- yes, common sense- lets try, lol.

Hey Maineman- when a die clash is deep, technicians do what amounts to almost grinding down the die to erase the clash, sometimes the go so deep that it effects the die detail, like the column you're referring to.

liveandie, thanks,that makes sense now and I see where the clash would have been with the back of lincoln's neck.So basically we have an overpolished die due in part to a clash.

Clash is usually the logical conclusion for overpolishing, considering the placement of the polishing, effacing a portion of LIBERTY and Lincoln's neck clashed on the reverse looks like the precise reason.

The Memorial bays on the right side show severe polishing lines as well as underneath LIBERTY by the shoulder. In hand, this coin is probably littered with polishing lines. When you see some funky thinned out devices, look for those polishing lines.

It would help as well if you would post photos of the entire coin ... obverse and reverse ... along with your normal detail photos.
Often subtle clues lie in the area that we did not think to look ... and your detail photos do not support that input or evaluation.

By the way, I never said I didn't see the column. Your wording led me to believe you could see the indentation of the Y of LIBERTY on the reverse, and I couldn't. Upon re-reading the post, you did not say you could see the Y on the reverse as I had thought you did.
End result is still the same, the curved column and thin Y are the result of die overpolishing, likely because of a die clash.

Thanks for clearing that up coppercoins, I thought maybe the pics were viewed differently on different computers.Again, I appreciate the education.
