Hello, Just need some thoughts on this coin. I see the double on 5 in date and what looks to me as double on face..coins also appears have bubbles or bumpy surface on both obverse and reverse..with a portion of the reverse (east of memorial..shiney) also has filled crack. Is there a known variety for this type? Coin is BU Thank you
The coin appears to have been Struck Thru a thin layer of grease! Hopefully Mike Diamond will see this Thread and post his comments about the coin. I traded him a 1995-P Lincoln Cent that had somewhat similar doubling on the "5" in the Date and it is thought that this kind of doubling occurs due to excessive pressure exerted on design elements because of the thin layer of grease. The Orange Peel effect in the fields is also evidence of the coin being Struck Thru a thin layer of grease. Frank
Seems like there are a lot of different things going on here. The face seems to show "split-line doubling", which occurs when the copper plating splits under tensile forces set up by the strike. The doubling of the date appears to be due to die deterioration. The broadly dispersed bumps on the obverse seem to be blistered plating. The irregular texture on the reverse appears to be the orange-peel surface of a late die state. Finally, there appears to be a die gouge or die dent passing through the S of STATES. I see no evidence of grease on the dies.
Thanks guys for your feedback..any thoughts on premium? I know the split line is not very dramatic but interesting coin given the date is one for known errors.
Among the various errors here, the die gouge is the most significant. It may increase the overall value to perhaps $10.
No need to thank me! It appears that I was off the ball on the assessment of what happened to the coin. Maybe I should keep my big mouth shut or in this case, my thoughts to myself. Anyways, I will stick to assessing the errors I know and quit trying to assess the ones I don't! Frank
Never do that! How would you learn? I rarely learn from the things I already know, I seem to only learn from my mistakes. As all mean are created equal (this is self-evident), I must assume you may learn from your mistakes as well. Never give up the opportunity to learn. OK, preface the statement with, "I am not an expert," or whatever, but don't "quit trying." I certainly won't. I like this stuff.
Just a thought--the surface bubbling could be due to corrosion of the zinc core. All it takes is some impurity or pinholes in the plating to set the reaction in motion. The resulting zinc compound would take more space and push up the plating in areas. Just one possible scenario...I can't say for sure.
Folks I much appreciate everyones thoughts and opinions. If it were not for different views on any subject we would all think the same. We have to appreciate those that have a better understanding of the things we do not..learn and share..then perhaps we too can do the same someday.
While subsurface corrosion can produce blisters, they tend to be larger and less broadly distributed than conventional blistered plating. Blisters caused by subsurface corrosion also tend to "pop" (rupture), while conventional blisters don't. Conventional blisters are evidently caused by gas expansion. On off-center strikes you'll only find the blisters on the struck portion.
Mike, If the orange peel surface is due to a late die state on this coin, then what is the cause of the same condition on Proof Lincoln Cents (mainly) from the 80's to current? With the amount of care, repairs and resurfacing of Proof Dies to remove any and all irregular surfaces on Proof Dies, could this truly be the case with them as well? I theorize that Grease may be the culprit in some cases for this effect on some coins and not just due to late die state, especially when it comes to Proof coins! I have seen many times, how grease is dispersed on two pieces of metal when they are slammed together with great force and that the dispersing of the grease on the two pieces of metal is very similar in appearance to the orange peel effect on many coins. Please help me here!!?? I may be almost 55 years old but my mind is still mostly intact and I just can't comprehend how that most of the irregular surfaces on coins, can be explained away so easily, as due to a late die state! The Copper coating on Copper coated Zinc planchets is extremely thin and fairly soft. Therefore, the pressure exerted on the surface of a Cent planchet (Copper coating) as grease is being forced across the surface of the planchet and especially outwards (away) from design element during the minting process, must be extreme and must have many other effects than just obliterating some of the Lettering in the Legend or Motto and/or Numbers in the Date.

Hi Folks, I have almost a full roll of these with the die gough in same place...most have alike blistering some with less...all have the same orange peel...there are few more with like split line..a few with date double..most less than this one...some with none but with all the other errors. I'm thinking of putting them up on ebay as one lot or perhaps here on cointalk. Do coins sell on this site well or would I be better off on ebay? Thanks
I'm not familiar with the proofs you describe, so I cannot make an intelligent comparison. On business strike cents of the zinc era, the lubricant responsible for "grease strikes" is smooth and viscous and imparts no texture of its own. I have not seen a single grease strike that leaves anything resembling an orange peel texture.
I will dig out some of my Proof Cents and if I still have any with this strong effect, I will take a picture of them and post them here! If I do not have any, I can purchase some from a local Coin Dealer that I know. I don't understand what you mean by saying, "the lubricant responsible for "grease strikes" is smooth and viscous and imparts no texture of its own"!!?? It doesn't matter what type of lubricant it is and that it is smooth and viscous. When the lubricant is between two objects and is forced across their' surfaces with great force as in the minting process, it will spread across the surfaces and generally be forced out from between them. Under these types of pressure, the grease or lubricant will not only move at high speeds but also heat to fairly high temperatures. This speed, heat as well as the forcing of the grease across the surface of a planchet and especially away from design elements, must effect the planchet in some manner other than obliterating Lettering, Numbers or even design elements.

Whoo Hoo! I have always wondered what that was called. I remember not too many years ago, this had NO name. :thumb:
