Okay, please bear with me on this. I have found a lot of LMC's that are silver/grey/gold/etc in color and it is pretty easy to determine which have been bathed in acid and which have been electroplated as part of an experiment of some sort. This one is different and I could use some help in determining how this happened. As you can see from the pics, only part of the reverse is affected but all of the obverse so, if this was electroplated or dipped in acid, how did they get the reverse only partially affected and all of the obverse. Also why, at the transition area on the reverse, are the letters raised where they are silver/grey. If it where dipped in acid you would think it would be the other way around, right? Then I thought it was paint,(I mean,it has to be paint, right?) so I did a small scraping on the side of the rim and all it did was make that part of the rim bright and shiny with no copper color in sight (see last pic). Please also note that the silver/grey area extends far down the rim on the reverse. I have puzzled on this for several days to no avail. I am sure someone in here has seen this before and/or knows what this is. I could really use some help here. Thank you for your time and opinions.      |

I'm thinking acid bath. I would think that if it was a plating issue the unplated area would have luster. As for how the reverse got that way with only part of it like that, I would guess it was obverse side down in acid with whatever container it was in on an angle to make it deeper on the one side.

Thanks LincolnGuy. That makes sense and is better than any explanation I have thought of, but then how did the reverse rim get dipped all the way to 6 o'clock on one side and 2 o'clock on the other.

Perhaps the coin has been soaking, partially resting on another coin at an angle in acid? no more than 1.5mm deep.
That's MY guess, anyway.

It is a genuine partially plated Lincoln error, nice find  It appears to be uncirculated or at least high AU so the obverse should have some luster although it would not be as strong as copper luster. I am inclined to think the dullish appearance is due more to your photography since the reverse does not appear to have much luster either. Zincolns are plated in an electrochemical bath and the dark grey line is a side effect of the planchet being only partially submerged in the bath. For comparision, here is another one with a bit more plating and the same transition lines-  |

I don't see any luster present but I am not familiar with this type of error

The surface should be smooth not bumpy. I've seen worse:  |

Looks like an authentic example of partial plating.

Well, that's exciting! Thanks to all for your input. Another first for me. How much fun is this hobby of ours!  A quick question: As I have no idea of value, is this slab-worthy or will a 2x2 be appropriate? |

I know what you mean, Dar, I didn't even know partially plated cents existed until today.

It is a genuine partially plated Lincoln error, nice find I'm working on some of my ikes in the general same field of total or partial clad missing. Don't know if cents and Ikes are in the same area. |

yeah your example looks authentic. It looks like there there might have been a 3 coin pileup, with yours in the center. It looks like there may have been some agitation going on there, and all 3 coins were stubborn and overall refused to dive in the bath individually.
cool find !
