1992D LMC - Error ?

What kind of Error or not is this Coin ? What are these Lines ?

Linear plating issue where the copper plate reacted with the zinc and didn't bond properly, or possibly roller marks on the zinc blank that didn't get struck out

 

Also.. Extreme Die Deterioration caused DDD on the Date and Mint Mark. Reverse looks like a Misaligned Die Strike. Interesting looking Cent.

 

Fun coin to find.

 

Linear plating bubbles. Not an error, just caused by zinc dust trapped beneath the plating layer.

 

It's an error in my book. And according to Error-ref.com

http://www.error-ref.com/blisteredplating/

 

1. If you want to call it an error, it's an error of the lowest order like machine doubling or a misaligned die. So when I say "not an error," it's short hand for "within mint tolerance to the extent that you see them very frequently." I personally do not consider any of these to be worthy of the term "error," since it is only an "error" in my opinion if it is outside mint tolerances.

2. Error ref lists many things that aren't errors just as part of the minting process (for example, they have write ups on varieties, which are not the same as errors). So inclusion there doesn't automatically mean it's an error, just part of the minting process they considered worthy of a write up

 

And I personally don't agree with your opinion.

Sorry.

 

Do you call a copper cent that weighs 3.12 grams a "rolled thick planchet error"? Mint tolerances for "errors" do matter in whether or not we call a coin an error.

 

Oh Boy, Here we go again .

 

The original subject was not about the weight of the coin. It was about the Linear Plating Blisters. I and many others consider it a minor mint error.

And no to 3.12.. that is definitely within tolerance.
I understand that and wouldn't call it an error.

 

Very nice looking background. It's definitely a keeper in my opinion. Thanks for sharing it.

 

Send it in to a TPG. They will slab anything these days. Then it goes up on Etsy for $50K.

 

I think Sam raises a fair point here. What are the tolerances for things like surface finish...etc.? Something that doesn't look 'normal' doesn't mean that it isn't. I think that needs to be kept in mind.

Re: linear plating, the example at Error-Ref shows an irregular pattern. The specimen above shows continuity of direction on either side of the coin. I don't know that linear plating blisters can't be less random and more ordered, but this has me thinking there is a different underlying cause. Something in the zinc substrate, perhaps during the rolling operation or perhaps something else.

I think this is not a case of linear plating. Looks kind of like a 'time-saver' finish from days of old when I worked in a sheet metal manufacturer. Maybe damaged roller surface.

 

Definitely an error, in my opinion. An error that the mint started using zinc with a copper plating, so anything from mid 1982 on, is an ERROR to me.
Thanks for the post though.

 

How about 'plating anomaly' ?

 

Haha you, I will not argue with, Fred. So whatever you think it should be called lol

 

Very common linear plating blisters. I’d keep it because it’s only one cent and the blisters are everywhere. It’s a mint error as they are not supposed to o be there.

 

SHARP KOIN

 

It is my opinion that any product that leaves US Mint and does not meet the Design Acceptance Criteria is an error. The question is "to what degree are they desired by collectors".
