Major Doubled Die reverse 2017-P Effigy Mounds quarter - Updated - Machine Damage Doubling

Manorcourtman · March 24, 2017 5:51PM

According to Dr. James Wiles: " the doubling is the result of machine damage doubling on incuse design elements. It is not a doubled die." Thanks for all the input and comments!! The Doubling is still fantastic!!!

I'm not sure how this happened but it is an extremely nice Doubled die in my opinion. I have found different stages and varying degrees of doubling. The 7 in 2017 in doubled nicely along with the E in E PLURIBUS UNUM. Opinions on how this happens with the new minting process are appreciated! Enjoy!

Nice find!

Manorcourtman · March 24, 2017 6:03PM

I'm wondering if it could be a large date over a smaller date or something along this thought?

DCW · March 24, 2017 6:09PM

Wow, best one in years!
What location was this one found?

BLUEJAYWAY · March 24, 2017 8:43PM

Good catch. Very pronounced doubling. The hunt is on.

ChrisH821 · March 24, 2017 10:25PM

That is quite interesting... I'll have to start searching for them.
To me it looks like a small E under a large one.

mannie gray · March 25, 2017 12:01AM

Wow!

tincup · March 25, 2017 5:09AM

Nice!

sparky64 · March 25, 2017 5:16AM

Nice find and nice pics as well.
I hope this gains traction.

PocketArt · March 25, 2017 5:22AM

Awesome discovery!!! I still haven't come across any 2017 change, and will be sure to look for this one. Way to go Manorcourtman- interesting variety!

ricko · March 25, 2017 5:44AM

Wow.... that is major... Great find... going to the bank this week for some rolls...Cheers, RickO

Better make it a ballistic bag ricko

ricko · March 25, 2017 5:46AM

Hey Chris, I will ask for one....just to watch the 'deer in the headlights' look on the teller's face... Cheers, RickO

dpoole · March 25, 2017 5:51AM

Clear doubling.

I thought modern production methods prevented this sort of thing. What gives?

ElmerFusterpuck · March 25, 2017 5:57AM

Cool and wow. Along with the doubling, that 7 reminds me somewhat of the 1847 over small 7 large cent.

joeykoins · March 25, 2017 6:11AM

Congrats, dude! Nice modern day find. Now that you gathered the troops, off we go to the hunt.

CaptHenway · March 25, 2017 6:26AM

I am stumped. Can we please see an image of the full reverse?

I will get one up later today. I will post a second coin also with a variation on the E also.

DCW · March 25, 2017 9:58AM

Well, where are these turning up?

On a BST near you real soon.

Azurescens · March 25, 2017 10:24AM

Looks like a bit of hub doubling and a dash of mechanical doubling... right?

acloco · March 25, 2017 12:47PM

WOW!

Heavy 7 over Light 7? That is what this looks like.

DoughDeo · March 25, 2017 3:29PM

Based on images available online, I see Business over Proof.

Anyone have both in hand to compare the 7 and E?
OP: can you post more pics?

PocketArt · March 25, 2017 3:53PM

Rolling the dice- just bought a bag from the mint, and a couple rolls on Ebay. I'd really like to find one of these....but...

Thanks Manorcourtman for the heads up!

CuKevin · March 25, 2017 6:47PM

Great find! I'll be watching for more news.

Manorcourtman · March 25, 2017 7:11PM

So I've been taking more pictures and studying the coin further. I have now found it to be doubled on the upper letters as well as the date and E of the Motto. First I'm going to post a pic of the coin since no one has probably seen one. Then I will post pics of the doubling. I used about 5 different coins to get the pics because I discovered multiple examples that are not quite the same. Please forgive my multiple posts to get them all up!

First, I think it is some type of large letters and numbers over small letters/numbers. I see on top doubled letters but they are smaller in size. It is most definitely Doubled die of some sort. There are notches and clear split serifs. The first pic is NDS of MOUNDS on the top of the coin. The arrows point to the doubling. ONLY where the arrows are pointed is the smaller letter doubling.

Pic 2 also shows remnants of the small letters

Manorcourtman · March 25, 2017 7:16PM

Pic 3 shows the same while pic 4 shows a different example of the doubling from a different coin. The 4th pic definitely shows a small D and S.

A smaller D and S is evident here:

Manorcourtman · March 25, 2017 7:22PM

Pic 5 shows notches from where a smaller letter should appear, but the letters are ghosts and don't appear. Just what I believe are the tops of the letters:

Pic 6 shows what I believe are the top notches of the smaller letters that are underneath the large letters

Manorcourtman · March 25, 2017 7:27PM

Here M and O are nicely doubled and smaller. I don't claim to be right or an expert!! Just my opinion. Other opinions are most welcome!!

Tetromibi · March 25, 2017 7:38PM

Awesome find! Thanks for the pictures.

P, D, or S??

Bank Roll? US Mint Roll?

mannie gray · March 25, 2017 8:49PM

Awesome find !
That is crazy cool!

ms70 · March 25, 2017 9:09PM

That's unlike anything we've seen in a long time.

CaptHenway · March 25, 2017 9:19PM

Excellent pictures, and now I am even more stumped by it!

CascadeChris · March 25, 2017 9:27PM

Who wants to guess how quickly the 100ct bags go dark

MedalCollector · March 25, 2017 9:45PM

Incused lettering has some weird effects. I wouldn't be surprised if it was a doubled die or die wear.

Rob85635 · March 25, 2017 9:59PM

Darn, another P mint error that doubtfully I will see without paying a premium for. I need to move further toward Philly.

Bodin · March 26, 2017 12:06AM

Am I a jerk if I'm saying this reminds me a lot of the '84 olympics $1 "ddo", where the incuse lettering had doubled with split serifs .....but it was determined to be a result of die bounce on incuse lettering.

That was my first thought.

illini420 · March 26, 2017 3:49AM

Cool find...

At the last Long Beach show the Mint was there and they had a change machine that was giving out the new 2017-P Effigy Mounds quarters. I got a bunch of them just for fun to give out to folks at the coin club and to use in change... I took a quick look at a few of them before spending them all and didn't notice anything special... maybe I need to start looking closer at the new stuff

TennesseeDave · March 26, 2017 7:05AM

Thanks for the heads up, I just ordered some from the mint. Maybe I will get lucky and find one or two.

Bodin · March 26, 2017 7:35AM

This is what I was referring to:
1984 D $1 Olympics
It was determined NOT to be a ddo

CaptHenway · March 26, 2017 7:37AM

Thanks for those pics.

Bodin · March 26, 2017 7:37AM

They seem to be two different things. The olympic coin doubling is the same size. The ones OP posted look to be large over small.

kaz · March 26, 2017 7:59AM

very interesting and mysterious. cool find!

I'll say this last thing then let the actual experts weight in(because this would be an AWESOME DDR discovery)
I think this appears to be large over small because when the loose hub bounced on the incuse strike, the bounce would only barely strike leaving a smaller impression since the "full" lettering wasn't struck.

tincup · March 26, 2017 8:35AM

Bodin, thanks for those pics. Looks to me like there might be something similar going on. Those pics also show examples of a 'large over small' type of doubling.

Something that puts some questions in my mind Manorcourtman is the statement 'I discovered multiple examples that are not quite the same. " That makes me think there is some other mechanism that may be occurring than a doubled die. Finding multiple examples with differences would not seem appropriate for a double die... unless of course there are multiple doubled dies that were in use. Like the Minnesota doubled dies?

These definitely require more study... if a for sure doubled die, then awesome!

Manorcourtman · March 26, 2017 8:39AM

I'm going to post more pics later. They will be different examples than posted earlier. Thanks for the input everyone.

epcjimi1 · March 26, 2017 10:00AM

Remember a couple years ago the idea of the US Mint seeding errors to increase sales / interest? Sure seems strange to see an error of this magnitude on a common coin, when it hasn't happen for a good long time.
