Oddity I picked up off ebay. I like ragged clips and this seemed to just have a lot more going on as well. Hoping folks can look closely at it an comment on what exactly is going on. The clip is good, but particularly straight so different from most ragged clips I see. The collar issue seems good as well but what is that going on with the rim below the date? And that grease on the back, is that struck through retained or after the strike. The reverse has that shiny look of a struck through, and the grease looks like it was smeared by feeder fingers. Guessing a lot here. But I see that type of grease on coins from BU rolls so thinking it is some minting issue. Thanks in advance for any comments to help me out with all the bits going on with this one. 1955 Lincoln Wheat cent mint error - ragged clip, partial collar and grease     |

Nice multi-error coin & like those edge photos. I'll say after the strike on reverse. Clip caused the rim error I'm guessing?

Nice. That channel on the obverse bottom reminds me of a coin posted a few days ago  John1  |

 I'm enamored with ragged clips (and slag inclusions) as well. Nice shots of the rim. That area of the rim under the date looks like it might be incomplete from the upturning machine or an abnormal Blakesly effect? I think you nailed the grease on the back as being machinery grease from the mint. I've seen it many times on coins from BU rolls as well, dropped on the coin sometime after it was struck. I've noticed 3-4 different types of grease on BU coins. Some almost clear, some with a greenish hue, some blackish like yours with what looks like microscopic sparkly granules in the grease. Words of encouragement are one of the major food groups.

Great example! Don't see too many ragged clips floating around out there.

Rim shot. Crowd Laughter and applause.
Oh... you mean those great pictures. Nice find as always TB. I like the clips of all sorts. Haven't found a partial collar yet. Can the flat area be on more than one side? I'd think not.

Partial collar issue also for this one.

Thanks for the great comments! I was out all day on a coin buy a couple hours away and just sitting down to see what's going on. Still wondering if anyone has a more clear picture of how that grease gets on the coin and at what stage of the process. Many of the struck through coins I see have a very rough, granular texture and I kind of think this is what the grease would look like on those. If I scraped this off, which I'm not going to do, would I find a typical Struck Through Grease look? |

Hello TB. I have to say I have viewed many of your posts over time and you have had some excellent finds. Great job!
I am going to play "devils advocate" here (PLEASE.... NO OFFENSE) because I TOO have some questions, and would like to learn, about what looks like possible grease on the reverse in which you are referring. I too have found many older cents with this same type of substance on a coin and have always wondered what exactly it is.
My first thought is this, question to follow- This coin is 66 years old. The clip is very nice. It looks to me that this Cent has definitely seen some circulation. I say this because of the smooth rounded and sloped edges on the rim and the metal along the clip that appears to be worn and smooth (once again... no offense, great coin). If this coin is 66 years old, and has been circulated for that amount of time, my question is how can there still be die grease on a coin of this age? What I do think I can see is possible striated lines in the potential grease on the reverse lending to what may be original grease, don't know, thus the reason for my question. By no means am I trying to take away from your coin or post at all. It is a great addition to your collection, one I'd love to have, but I also have questions about the grease issue. Thanks.

Some almost clear, some with a greenish hue, some blackish like yours with what looks like microscopic sparkly granules in the grease. Not sure if you caught this above. Most (all?) production lines use grease on the machinery. The older the machinery the more grease required. I have been curious myself and found the following info. Link to "Lubrication 101: The four types of lubricants" (Machinery related.  ) https://vibralign.com/machinery-mai...icant-types/For those that don't like to click links here is some interesting quotes from the article. The very first sentence may explain a lot regarding the possibility of excess grease "dripping" from equipment, before and after the striking of coins. Quote:
"A lot of times in the industry, lubricating machines is a task given to new employees because it's thought to be a job for newer workers or apprentices. " Quote:
"There are 4 types of lubricants: Oil, Grease, Penetrating Lubricants, and Dry Lubricants. The 2 most common lubricants you'll be dealing with daily are oil and grease..." Quote:
"Greases come in a variety of consistencies, the thinnest being similar to ketchup, the thickest coming close to a block of cheddar cheese. " Quote:
"Don't Use Grease When:
Your machine has fast-moving or fine parts and grease could slow it down or create too much resistance
If you need to keep the area clean, moving parts can fling grease around
You have fine or fast-moving mechanisms where thick grease would create too much resistance" A new employee may not know about these "don'ts" or may over-grease which could lead to "flinging grease". (I digress but this would be another great name for a rock band, as Dave Barry would say!) I'm pretty sure the grease on your coin showed up after it was struck. Whether the grease dropped on it or the coin slid through it is hard to say. Words of encouragement are one of the major food groups.
