Just found this 1980 LMC searching rolls this afternoon from my local bank. Its pre 1982, so I don't think this is the zinc oxidation monster. Not sure, but there also seems to be some kind of doubling by the date, Lincoln's shoulder, top of head, extra columns on the Reverse in the Memorial and by the letters in "one cent." Resident Experts- Help on this please!        |

I don't know- I looked at your nickel and the surface texture seems different. Your nickel seems to have round beads on the surface- this coin doesn't, it has swirling lines going in different directions over the entire surface
I'm not saying that someone didn't chemically damage this coin,(I hope not!) but it looks different texture wise and doubling features.
Thanks for posting the pictures for me to see!

That surface is typical of a copper cent that was acid dipped. It's just damaged.
Thanks,
Bill

Definately post mint because the devices are affected.

Thanks for all the responses!
I'm going to post over at Coneca for Mr Diamond's Opinion also.

Different response- Not Post-Mint Damage.
BF Neff from Coneca:
"This is a serve case of the "Orange Peel" affect. Beleive it or not, it is a natural function of die aging. As the die ages, metal flow of the planchet strips away the surface atoms of the die, causing lines, groves ,ridges to form on the die. A similar example is the ripples formed by water flow over a stream bed or the washboard effect on an old country road.
In this case, the die is probably in a very late die state (VLDS) and is just about at the end of its life."
BJ Neff.
Going with BJ'S answer- is there any doubling on this coin, especially around the letters TES of States and the 2 columns in the Memorial?

2 new pictures- check the A & M in America and the TES of S Appears to be doubling?   |

Further explanation from BJ Neff: This is NOT a mint "ERROR", it is a natural die progression and the doubling is Die Deterioration Doubling. Hold on to the coin - not often that you see a die that deteriorated, and its a good conversation piece. (Thanks again to all who responded!) chuckster 125 |

Another difference of opinion from Mr Diamond!
"I have to dis-agree with BJ. This coin was modified outside the Mint.
They're often referred to as "Wire brush jobs" or "rippled surfaces"
Exactly how the texture is produced is unclear, but some sort of rotating brush is probably employed to generate heat and friction. You see these from time to time on e-Bay and I have one or two knocking around in my reference collection on fakes."
3 different opinions
1 Coin Community Forum Consensus- Acid -Post mint Damage-
2. Orange Peel- VLDS-
3. Wire Brush /Heat friction Fake coin.
Almost sorry I found the darn thing today :(

These are termed "rippled" or "wire brush" coins. The theory is that a rotating brush generates heat and friction and moves the metal around. At any rate, it's a form of mechanical alteration. It's a commonly encountered form of flim-flammery.

Wire brushing makes sense to me because I was thinking acid treatment but the color was all wrong for that. The coin has a nice orange color but if had been in acid, it would be discolored.

Hi All,
Sorry guys, I still disagree. It is simply damage caused by an acid bath:-) I made a ton of them in high school many years ago. Copper cents looked just like this when done. It has nothing to do with heat or a wire brush. I have a few around here someplace and as I get a chance I'll photograph them and post the pics. I made them so I know from whence they came. They were part of a science experiment. I don't remember all the details but electricity was involved. Again, vague recollection but it had to do with a lemon, the penny, and some nails to make a battery.
Thanks,
ill

You can stick a nail (or paper clip) into a lemon for a negative electrode, then use heavy copper wire for the positive .. did you use a penny to replace the copper wire to complete the battery?
And creating the lemon battery did that to the pennies?

I have a Canadian cent with an interesting surface feature...I'll post that sometime. I cannot decide if it was tooled, or a mint error. And creating the lemon battery did that to the pennies?You could probably pull copper ions off a penny by using another metal that produces a strong galvanic potential-- such as zinc. You can actually witness this everyday with your corroded Cu/Zn cents. Note: I was wrong here--the copper pulls ions off the zinc, causing it to form compounds  Edited by KurtS
