Rykel Posted November 2, 2023 Share Posted November 2, 2023 I posted this 1984 Lincoln cent coin in a coin forum some months ago and I wanted to share it here to get some more opinions. What type of error is this? Link to comment Share on other sites More sharing options...
Mike Meenderink Posted November 2, 2023 Share Posted November 2, 2023 That's a die crack obv, Die chip or strike through rev with plating blisters on a crappy old penny. Spend it Link to comment Share on other sites More sharing options...
Sandon Posted November 2, 2023 Share Posted November 2, 2023 Based on the photos, I think that the raised line across the obverse of varying width is most likely due to a defect in the copper plating on this 1984 cent. Such defects are quite common on earlier (1982 to mid 1990s) copper plated zinc cents. The narrow raised line on the reverse that runs from the right side of the base of the Lincoln Memorial to the rim, on the other hand, is likely a die crack. Neither of these defects is usually regarded as a significant "mint error" that would be of any value to knowledgeable collectors. The coin might bring a small premium as a novelty. You are welcome to collect such coins if they are to your liking. Rykel 1 Link to comment Share on other sites More sharing options...
dprince1138 Posted November 2, 2023 Share Posted November 2, 2023 (edited) The line is very typical of a die crack. From what I have seen, die cracks can be either raised, such as in your image, or a true "crack".

All the die cracks Ive seen on the coins have been raised. zadok 1 Link to comment Share on other sites More sharing options...

Considering the date and appearance I would tend to agree with a linear plating blister from gasses building up below the coin surface. That would collapse if you gently pushed down on it with say a q-tip. It could also be a scratch or break in the outer cladding, which you may not see without good magnification. That can cause corrosion to push the thin cladding up, and randomly widen in spots like near the date and shoulder. This would be a solid corrosion blister in the same general plating defects category at error-ref.com. https://www.error-ref.com/blisteredplating/ On 11/2/2023 at 12:01 AM, dprince1138 said: ... die cracks can be either raised, such as in your image, or a true "crack". Same thing. A true die crack is raised on the coin, but typically in a thin jagged pattern. Die cracks can present as being significant when they are bi-level, but it doesn't have that appearance.

Popular Post Lem E Posted November 2, 2023 Popular Post Share Posted November 2, 2023 (edited) IMO it’s too straight to be a die crack. Not saying it can’t happen, but usually a crack will follow the profile of something along its way and veer one way or another or hit a gap and stop. I do see sections that look like cracks and some that look smooth and bubbled. I say plating issue given the year of the coin and the issues they had with plating during that time. Still have them now. May be a combination of both. Edited November 2, 2023 by Lem E zadok, Rykel and Hoghead515 3 Link to comment Share on other sites More sharing options...

That would be known as a cracked planchett then wouldnt it? Instead of a die crack. Any crack in the die it is gonna leave a raised line. Probably meant a planchett crack and misidentified it as a die crack. Mike Meenderink 1 Link to comment Share on other sites More sharing options...

Yes, a crack could be either a die crack, which is raised on a struck coin, or a planchet crack which would be incuse. But he said a "die crack could be either ..." which might make sense if you take out "die" there. I don't think it's either, but may be a crack in the thin outer cladding which bubbled up from corrosion as it appears raised and randomly wider to me.

powermad5000 Posted November 2, 2023 Share Posted November 2, 2023 @Hoghead515 I have a Merc with a partial "crack" and you are correct. It was mint error graded as Defective Planchet, Planchet Crack. An actual split in the coin itself is a planchet issue. As @EagleRJO aptly pointed out, any crack in the die is going to let metal flow into the crack of the die during the strike which will cause a raised line on the surface of the struck coin. I agree with the others that this coin has an obverse linear plating bubble, and the reverse has a small die chip on it by the memorial as well as another small plating bubble. Maybe with the coin in hand this could be disproved, but I have seen too many cents of this era with a myriad of plating issues (cracking, bubbling, chipping) and on the OP's somewhat worn cent, the potential for the environment to aggravate these types of issues.

dprince1138 Posted November 2, 2023 Share Posted November 2, 2023 I would assume that a planchet crack is unique, relatively speaking. The crack in the bust is displayed on all variety sources (O-108). I have seen other cracks of this sort to varying degrees, but generally, they are small.

Hoghead515 Posted November 2, 2023 Share Posted November 2, 2023 I see now where he said true crack. I apoligize. I thought it said, "die crack or true die crack". Thats my bad @dprince1138. I read your reply wrong. Ive not had much sleep all week. We been working days and nights both. We was off last night but I couldnt sleep. Very exhausted. I read your reply wrong. But I dont think its a craked planchet if thats what you meant by true crack. Parts of it look raised to me in the picture. Looks like plate bubbling or something like that to me also.

Rykel Posted November 2, 2023 Author Share Posted November 2, 2023 I was thinking along the lines that possibly there was a crack in the dye and that caused the blistering. The combination of two errors possibly. Link to comment Share on other sites More sharing options...

The combination of two errors possibly. Two totally different things here Rykel. Plate blistering (or blistered plating... tomato/tomaaato) is basically a chemical reaction underneath the minuscule micron layer of copper platting that coats the zinc core of the Cent. A die crack is considered a die event which is completely different and has no relation to, nor would it create, blistered plating. I like your train of thought though in thinking "outside the box".

However, per my post above there could have been a crack in the thin outer plating of the coin which allowed corrosion leading to blistering. As noted more info is needed to really narrow it down.

It is raised up and solid. 100% raised out of the coin solid as a rock. So what you're saying if it was caused by gases and it was a blister it wouldn't be solid correct? Does this mean it is a die crack? Link to comment Share on other sites More sharing options...
