As biokemist said in the other thread, this coin exhibits die wear - not a doubled die.

Very common on the late 80's cents, but I especially notice on 87 and 89.

Follow up:
(I am thankful for the seasoned posters who help educate.)
So this is a worn die, but not a "doubled die", I understand.
So this would be Abrasion doubling?
And the horizontal mark just under the bow tie (I admit the poor photos make this hard to see)... and another place even more difficult to see.... thought maybe this is evidence of a "Die Clash"
... if I think about it long enough, this becomes a BU grade, and very rare (LOL... just kidding!! ...)

It's not really abrasion doubling - that's caused by abrading (polishing) the die. This is simple die wear...that's all. No doubling.
I cannot tell what the mark is you are seeing under the bow tie.
It's possible that this coin could possibly be mint state, but it looks more like an AU to me.

Seriously, respectfully, how does one distinguish between a Numismatic Doubled Die and ordinary household doubling (two images, or image twice) as clearly seen on this coin?
The "double" (or two)dates is obvious even in my poor photos and easily seen by eye with a low power hand lens. And the "double" (or appearing twice)of the first letters of Liberty can just be made out in these photos.
I can see where wear could be playing a role given the shallow L in Liberty and the way the "In God We Trust" inscription tails off at each end.
Sincerely sir(s), I appreciate the expertise represented in your observations and comments, and I am eager to learn.
(BTW, thank you for the generous comment that the coin might be AU grade.)

Doubled dies are generally caused because of mistakes in the multiple hubbing die manufacturing technique. In order to properly impart a design into a die, a number of hubbings (or pressings) were necessary. A doubled die is caused when a subsequent hubbing of a die (impression of the design into the die) is not in alignment with the prior hubbings of a die.
So this is a matter of pressing a design into a piece of steel, and at least once in a while messing up that process.
The ONLY thing I can say to help is that your coin doesn't even LOOK like a doubled die. 1983-1989 cents are VERY notorious for exactly what you are showing - it is very common. Often called "shadow doubling" or "ghost doubling" it's an effect of steel molecules moving across the surface of the die. There is actually not ANY doubling on your coin - at all.

Ricardocody - I'm not sure where you're going with that post. This is not Machine Doubling - your post doesn't relate to this thread without more information. |

I have one more question...
But first I want to say to Mr. Coppercoins that I greatly appreciate his patience in bringing me along in this discussion and the generosity of his time. (To readers of this forum who may not know, Mr. Coppercoins "wrote the book" on Lincoln cents vis-a-vis the Doubled Die, et. al.)
(Please tell Mr. Piazza for me that I will not be sending the coin over for attribution any time soon).
I want to also call attention to (and thank) the owners and developers of this, the wonderful Coin Community Website, that make it possible for someone such as I to rub shoulders (so to speak) with the Mr. Coppercoins of the world.
Without further delay... My FINAL QUESTION... Numismatically speaking, is this coin anything at all?

umm...thanks? I was only one of a parade of people to publish books on the subject. I didn't write "THE" any book.
And no. It isn't. But this also doesn't have to be your final question. You are always welcome to post questions.

Ahh, but if you tell her exactly what she wants to hear she won't say that.
Different forum...

Hey guys! Awesome thread going here. I found this 1987 D penny with what I believe is 'shadow doubling' But what I was more interested in is the partially missing devices on the coin. I'm thinking its a planchet error, what are your thoughts? (Sorry for the sideways pics. I'm still very new to this)    |
