Hi All, First off, let me introduce myself. I"m British but have been living in the States for some 15 years now, where I am a full Citizen (through my company!) and I find is the place that I now call home. The Wife and I just moved back to California after spending the past 12 years in NY/NJ and have been in to "Collecting" coins off an on, both from the UK and the US for years. With that said, I would in no way call myself an expert, in fact, more of a beginner and learn something (many) new every day.

Hello to you all!

I'm a member of PCGS and have focused the past couple of years on attempting to put together a set of Morgan dollars. I've recently branched out to other U.S. coins. which brings me to my interesting find that I hope some of you might just be able to shed some light on.

Today I received a 1983 Proof Set and the included Lincoln Penny has some unusual abnormalities for which I'm not sure what the correct term is. It's almost a form of a Double Die but also a coin layering issue.

Looking at the pictures you will see that the "S" Mint Mark look as though it's been relocated a few millimeters to the North-West from where it was originally placed!

Looking at the date, the outside lower right of the "9" looks as though somebody has traced it with a Scalpel revelealing the Silver colored material underneath.The inside North-East of the "8" has the same effect as well as the outer South-Easterly point. The "3" has the similar marks on outside center mid-point if that makes sense.

The "L" and the "I" in LIBERTY each have a Silver line running down their outside East side edges. The left leg of the "Y" is also similarly effected.

Finally on the Obverse, the tops of almost all high points in "GOD WE TRUST" have Silver lines above their straight lined tops i.e. along the top of each of the three horizontal lines in the "E". The "R", the "S" in particular and the "T" (in that order) in "TRUST" look similar to the Mint mark in they look as if they've been slid down from where they were originally positioned by about a mm. You can clearly see a Silver "S" above and behind the actual "S" and you can clearly see the top of the "T" bar in Silver above the actual "T".

As for the Reverse, this is far less dramatic however there some very clear abnormalities. The under side of the cross bar in the "T" that is part of the work "CENT" shows a not so crisp line of Silver. Running up the right side of the memorial you can see an outline of Silver. Last but not least, the inside lower loop of the "C" in "AMERICA" also shows the same Silver trace. I say not least as the the coin has tiny traces of Silver all over the Devices but if far less a quantity than what is detailed in the above.

Just to be clear, when I used the term Silver in the above and merely describing the color that is present, not the metal composition which is almost certainly Zinc.

I look forward to hearing any and all thoughts and comments althogh will have to check in the morning as it's 2:30am now and I've had enough for tonight.

Cheers!
David

I'm worried that the pictures that I'm able to upload here are not going to be of highest quality. I'm also not very good at editing pictures so have placed the full size images in a zip file that you can download here: Staff edit - removed external link and external link data

Unfortunately, this is not an error and is not valueable / desirable. In fact, I've never seen it on a proof coin before, and it is called SPD, or split-plate-doubling. The coin is plated before striking and thus resulting in inevitable weakspots that tear when shoved into tight devices like the date and lettering.

I have seen it on Proof coins, not uncommon at all.
You should try to find a better one, split plate doubling is not a good thing.

When these coins are minted the metal flows out toward the rim. This is why you see this on the rim side of the lettering. The bond between the copper plating and the zinc core can not stand the stress. 1983 was only the second year with these plated cents and the mint still had major issues with the plating.

Yes, more of an undesirable coin than something collectible.

Thanks to all for your replies and valuable information. I'm going to hold on to this one as it's unique to me and although it's not of value, is a good reference point that I will use going forwards.

Has anybody seen this same affect on anything other than Penny Proofs? I'm wondering if this is more related to the Copper component at the surface, or not.

Good idea. Although as mentioned it does not carry a premium, but I do see it all the time that there are interested buyers who do pay more for these examples.

Oh you bet ya, split plating is a most common defect seen on the Zincolns.

I would think it is more related to the poor quality of today's mint product and certainly due to a thin Copper layer over the Zin core........

More of an issue with too much pressure during the strike. The copper plating is pierced through. Now the zinc is exposed. Sometimes the oxygen alters the zinc when it gets exposed. Sometimes reacts:

Not a good thing. Best to get a replacement if it is in your collection. If it is still in the holder/cello leave it there. That will slow down the breakdown process.

Wow, that's pretty dramatic! I'll keep an eye on these over the years and watch how they do.

Thanks again to all of you for the expert advice. Cheers!
