Looks like a blank planchet. It's worth a couple bucks.

It is probably a planchet. A blank and a planchet are steps of the process of making coins. It is either, blank (type 1) or planchet. (type 2) A blank is a cut out for a coin. A planchet has the rim setup process done, making it a planchet.  So the term "blank planchet" is an incorrect term. Edited by coop

Coop, Didn't you show a die/hub combo that reflected the plated parts of a plated cent are actually formed BEFORE the plating is added to the planchet?
The picture above contradicts that, just trying to understand the process...
Thanks,
Robert

Not sure if I have the right question or not. But the procedure normally is: 1. blank cut 2. run through upset mill making it into a planchet. 3. plated 4. struck The first three steps are done outside the mint as they buy the planchets that are already plated. (steps 1-3 done before the mint get the planchets) It is possible that the planchet could not be fully/partially/not plated before they were struck. It is also possible that a blank could also be not run through the setup mill and even be plated. It is also possible that a blank could also be not plated. I would think that they would watch for these, but like a lot of things, they can slip by during the striking process. I re-edited the image to include more information.  Edited by coop

Out of curiosity, what does the other side look like?

It's the same, it hasn't been struck.

Try this again,,,, Here is a pic of the post that made me think the plating was stamped on its own, before being added to the planchet Robert  Edited by Roberthas

Blanks are punched from coiled sheets of metal stock. Clad layers are bonded together in sheet form while Zincoln blanks are punched from sheets of zinc, milled into planchets, and then electroplated(all done by Jarden Zinc before delivery to the Mints). |

biokemist6, The image above of hub/die only shows one image,, the same image. This is what made me think that it formed the plating for one side. I even stated so in the thread and included that part of the thread. Another member chimed in and said this was news to him also.
The process you describe sounds like what I would imagine but the several images Coop attached that were FRONT and BACK of one image, not BOTH sides of a coin were what led me to thinking this.
I am unsure if you are pointing out two different types of coins above with Blanks are from metal stock(nickel, dimes), and Zincoln blanks (to make pennys?)
Maybe it is that I am not aware of what a hub and die are for since you point out they are not related to a blank/planchet?

All US coin blanks are punched from coiled stock sheets but Zincolns are the only blanks that need further processing(electroplating) prior to the formation of the protorim during the edge milling process.

I understand now that the hub is used to make the die
That was not clear before, I was wrongly assuming they were used in conjunction just as an obverse die and reverse die must be. (at the same time, on one coin)
It is good to know the process worked as I originally thought...
Thanks,
Robert

Here are the steps for die creation:  Not figuring the template creation and the stock preparation for the hub/die material. |

Hahahah, a guy on ebay calls it 100% off center error! |

I mean technically it is because on say a 60% off center error 40% of the coins details are present. So on a 100% off center error, 0% of the coins details are present. Also known as a blank planchet.
