I just received confirmation on my coin that it is a type of partially unplated Zinc planchet. And this is coming from a reputable error coin expert.

Did your reputable error coin expert have the coin in hand or see photos of it? Did he/she explain why it has the same lack of plating on both sides?

Respectfully, who? How many others did you show it? Did any of them agree with it?

It may sound like we are giving you a hard time about this, but I assure you we are not. We are just trying to help you understand.
Partially unplated cents do exist, but I really don't think that is what you have here.

I sent my pics to Fred Weinberg. http://coins.about.com/od/errorcoin...weinberg.htm
He stated to me "It might be a partially unplated Zinc planchet,
but it's hard to know for sure from scans/photos only."

Which I should have stated instead of "having confirmation".

I'm gonna send in my coin with a few others I have to get "officially graded and slabbed". Pictures tell a thousand words. But without officially having it seen, I do believe it to be a partially unplated zinc planchet. I have shown it to a few other coin collectors in my area also, and they say too, to get it checked out. It's not that I don't trust your words on it, I can't justify it being PMD or done on purpose. And yes photos don't do it justice.

Well now you didn't mention it was Fred Weinberg. You are correct about in hand vs. Photo evaluation but I'm still in the PMD camp personally. Keep us updated for sure

Closer images of the surface would help a lot. We had many partials in 1985 (for the 1985-D) that came straight out of Loomis and they had a different look. I like Fred would say it "might be" based on images alone but could go no further than that.

Also, remember, an opinion from a grading service is just that -- an opinion -- so if it does come back genuine don't be surprised if others disagree with coin held in hand. I've seen plenty of fakes in slabs over the years.

Here is what a genuine Unplated Zinc cent looks like. If it looks too perfect and is too shiny, it's almost assuredly a fake. If it has the raised lines running through it that match those you see Drew's first coin (that are diagnostic of plating issues) then it's a fake. The effects I see on your coin can be simulated by letting a cent sit on a hot surface for a time. I had Two Cents start to show such effect that I just picked off the basement floor and set on a hot surface of our furnace for about a year.

Congratulations on your find and your perseverance. Well done!
It looked genuine to me also from examples I've seen online. I can only imagine this look has something to do with the process used to plate the zinc with copper. Maybe it got sandwiched between two others during the process or low concentrations of copper in the solution?

Does anyone here have any info/video/images they can share describing the plating process from JardenZinc (the supplier of zinc planchets)? Thanks in advance if you do.

Actually found this at Jarden Zinc Facebook page. Video on planchet production.

If you don't mind my asking, what did NGC charge for slabbing it, excluding postage?

Just curious, but what would the value be on a coin like this?
