I would like your thoughts as to this 84S proof Lincoln.
Is this flat field doubling?
Is it really extreme flat field doubling?
Is it an RPM ?
Thoughts...
Update from James Wiles and kind of what I expected...
"Not an RPM. Machine Damage Doubling on both strikes, producing flat field doubling from the MDD of the first strike"
Some coins are just plain "Interesting"

Looks like an RPM to me
Unless it's a very deceptive issue with the plating, I'm seeing an RPM, and a heckuva nice one. No listing on Variety Vista.
How thick is the top of the "S" supposed to be? If that's the normal thickness then it looks like an RPM. Otherwise it's probably something else.
I think I see...
-Serifs, top/bottom ends of the “S”
-Curvature, i.e., no flat shelf-like step-like
-Heading into the N/NW
-The more I look at it... triple?
-So going to stop looking and say, very nice find and a mighty fine pic
Looks rounded to me and therefore a great find.
I had this proof tagged as flat field doubling but I looked at it again and started
to doubt my original conclusion. Still not sure but great eye by Hemispherical as
it is tripled.
Maybe someone has seen this die before and can add a comment but it looks rounded
in the pic and in hand as well.
The "sinker" was mad about something that day.
Three very hard whacks.
Look at the work harden "S" shaped halo surrounding the S/S/S mintmark.
Very cool find.
I have not seen that one before.
You likely have a discovery coin.
Well done!
Awesome photos man!...the fields look Iike boiling-hot oil...Congrats
Looks like an RPM.
but, I don't know what "Is this flat field doubling?" is.

I would call that an RPM....and it does appear to be tripled.... Really great pictures. Cheers, RickO
I have seen fractured plating on zinc cents that looks a lot like your coin, but it is typically not isolated to one small area like that, and you can see bits of the zinc core showing through. I will fall cautiously in line with the other responses and say that I think you have an RPM there. Nice find!

I will go against the grain here and say no because the top loop seems too "thin", as if it has been sheared off and moved by die bounce. But I would probably send it to Wiles just to be sure.

An exciting find IMO. Love the pics. The hunt continues. Peace Roy

@JRocco There you go!
Very cool find, for a guy with an even cooler name!

great clear pics and cool coin to
Isn't it surprising that this really cool proof RPM was (I am fairly certain) previously unknown?
It just goes to show that often the common coins don't get scrutinized.
Congratulations to @JRocco !
Thank you all for the opinions. I will send JW an email and go from there.
I'll share what he says when I know.
I can't wait!
Please let us know.
You have a nice RPM there.
Guess I now have a reason to look at 1984 proof sets...
Update in first post.
I guess my initial thoughts were confirmed,
But still a wild example of flat field doubling.
Thank you for the update. The assessment leaves me with more questions.
Still a neat looking Mintmark

JRocco you may want to change this thread title to something like: " 1984-S Proof Lincoln RPM refuted!" It might save some Cherrypickers from hunting for something that ain't. The original thread title might be easily overlooked?
I have seen many of these over the years in proof sets and considered them to be RPMs.

Wow - although I don't specialize in Die Varieties,
I have to admit, based on the photos, that it
certainly looked like a proof RPM.
Not the first, and not the last time, I was wrong

Good idea.
I know I would be searching for this one if I saw a thread showing it too.
@JRocco Thanks for the follow up. This is good information for the future.
Nothing doubled, but the MM. I still say it is a RPM
