I'm pretty sure this is not an acid job. Its the nicest I've come across like this.

Any ideas what its worth? Any body collect these?

How can you tell that it is a mint error, and not an acid job?

I sure don't know. I'm no expert. Someone here said acid makes the surface rough and bubbly. This one is very smooth, even though its discolored. Here are more higher mag pics.

How does one tell for sure?

Looks like you have a discolored Lincoln with the weight being 2.5g

where ever this Lincoln was - most likely outside because its discolored

i've seen that some graded unplated Lincoln, NGC puts the weight on the label which should be about ~ 0.2g less. If this was sent to NGC i think they would bag it but you could try ebay - you might get lucky

look at this unplated dime someone is buying - good grief !!!
someone will buy almost anything if someone calls it an error

I know the term 'acid job' is used somewhat freely in numismatic circles, but take it from me- copper metal will not dissolve in acid. There are other things it can react with, but acids are not one of them.

The only exception is nitric acid but then it's the "nitric" that's doing the reacting and not the acid part.

Does that mean you think its legitimately unplated? I think its discolored because zinc is less resistant to corrosion.

Not necessarily- it could also be plated over the copper with zinc. It looks like there are bits of copper color showing in your images, although maybe that's dirt?

Thanks for the input Snowman, but

The pics might not show it well, but for sure there is no copper. Its definitely not discolored copper.

With my scale I weigh lots of 1982 cents. The zinc ones weigh anywhere from 2.4 to 2.7 grams, so I am not surprised by the 2.5 gram weight even w/o the copper. Thats why I weighed it in grains also. I have no idea what the plating should weigh.

As for sending it for certification, what would a certified one be worth?

Wow! I never thought of that. Should I take a file to it?:angel:

I think its just dirty. Its pretty smooth. I'll look closer.

I'll ask you too. Is it even worth getting certified, even if its legit?

Good question. Here's an interesting discussion on unplated cents:

I would ask Mike Diamond to look at your images and give an opinion.

Thanks AG. I will submit my pics to coneca.

I agree no an acid job. But it could have been plated. I have a bunch of these and you can usually tell as there is indeed copper below that plating surface.

I sent pics to Coneca. Mike Diamond said its possibly legit. I'm going to send it to him. Only way to find out for sure. Maybe I'll get lucky. I will let you guys know one way or another.

I posted this pic in another thread some time ago but thought it was applicable here. I weighed each 1983D on my scale, and the both of them....
