1986d ddo penny 1 1

[SalRos315]

Hello,

I consider myself a newbie although I've been collecting my coins since 1984.

As I was going through my stash I came across this penny.

I'm hoping someone out there can tell me if I have a double died or otherwise. I hope it's a double died and discovery coin as I can't seem to find another one like it

[Mike Meenderink]

This penny has what is called machine doubling. It is not a DDO. This is common for many many coins. The hub that holds the coin die (stamp) was a bit loose and shifted  as it stamped this coin as well as thousands of others just like it.True doubled die coins look much different and are created by a coin die that has the doubling in the die itself prior to striking the coin. See reference material regarding Doubled die coins online for photos of true die doubling.

Hi SalRos315,

It could also be a matter of split-plating.  When the penny transitioned to more zinc and less copper in 1982, it created a nightmare for the pennies that today still ravage most.  Although your coin is less pronounced than the example below, you can see the effect.  You should see quite a bit of this on pennies from 1983.  I have been inundated with thousands of pennies just like yours.

Fantastic resources can be found in the thread: Basic Resources & Glossary

There are many anomalies that occur through the minting process that are not categorically defined as errors or varieties that I consider to be collateral damage. (gotta break eggs to make omelette)  The resources will illuminate you to some interesting and helpful information that will aid you in your coin hunting.

Right off hand, I would believe that this is a double strike condition.

[SalRos315]

Thx for sharing your knowledge. Very helpful indeed. I'm going to post a few more coins and hopefully y'all can give me some input on those as well.

You really don't know anything about coins do you @dprince1138.    @SalRos315 please disregard this information, it is completely false, your coin has what is known as split plating.   Split plating is very common on the zinc core copper plated cents made after 1982, your coin has no value over face value.   If you find it interesting and want to keep it that is fine, but it will never be worth more than the face value.

   I'm not sure from the photos whether this 1986-D cent exhibits strike doubling (a.k.a. machine or mechanical doubling) or split plating, either of which has no collector value, but it is definitely not a doubled die (not "double died"). A doubled die typically features crisp, clear doubling, with both images at about the same level, as on this "Redbook" variety 1972 doubled die cent:

change "have" to "has"

[GoldFinger1969]

So the true DDO condition has to be clear and material, like Sandon's coin's "LIBERTY" which is clear even to a mediocre grader like me ?

These other conditions -- while unique -- clearly don't have the magnitude of the "doubling" so they're not worth anything -- is that it ?

    Not necessarily. There are many minor (and less valuable) doubled dies where the doubling is only in a few letters or other elements and/or involves a much closer, barely noticeable "spread" between the two images. The difference is how the additional images occurred. A doubled (or tripled, quadrupled, etc.) die is created during the die-making process when the "hub" is moved between blows, resulting in all coins produced from the die, at least in the earlier stages of its use, exhibiting the multiple images. This is quite unlike strike doubling, which results from a die being loose in the press, split plating in copper-plated zinc cents, or die deterioration "doubling", all of which are considered worthless.

   I use the 1972 FS-101 or "Redbook" variety doubled die as an example because the doubled die characteristics are so obvious and because it is an example of the type of doubled die that would tend to have substantial value. There are eight additional less dramatic doubled dies on 1972 Philadelphia cents listed on NGC VarietyPlus alone. Lincoln Cents, Memorial Reverse (1959-2008) | VarietyPlus® | NGC (ngccoin.com)

To the OP, completely disregard @dprince1138's comment. He/she does not know himself/herself what forms of doubling even are. I agree with @Sandon that I cannot say for sure whether there is split plating or a different form of mechanical doubling on the date of your coin without better cropped and more clear photos of your coin. I can say with a high degree of certainty that it is however one of these forms of worthless doubling you are seeing of which hundreds of thousands were produced and it is seen as a lack of quality control as well as an issue the Mint faced when it changed to these copper clad zinc core cents. The surface issues are well known and continued over several decades.

Generally, I do not react to, or see, troll activity, but apparently, emojis are still visible, so I would like to present evidence of my claim of a possible double strike.

"On the other hand, there is mechanical doubling. This type of doubling, which is also known as strike, ejection, shelf or shift doubling, is not the result of the design on the die being doubled. Rather, this type of doubling occurs when the die strikes a planchet. If the die is not properly seated, it can move slightly or bounce during the moment of striking, creating a flat, shelf-like doubling. This effect will be different on all coins struck, so it is technically not a variety, but rather more of a striking error."

@dprince1138  You seem to be confusing double strike and strike doubling, two totally different things.  A double strike is a coin that is actually struck twice, strike doubling is just another term for machine or mechanical doubling.

This makes no reference to neither supports your claim of "a double strike coin". You are the only "troll" on this thread. When direct facts refute your statements you revert to playing a victim of said "trolls"which is laughable.

Yes, I was confusing the 2 terms.

Once, in an Austin, TX, city bowling tournament, I had 32 strikes in 3 games for an 834 series.

In a state PWBA pro-am no-tap bowling tournament, I had 34 strikes in 3 games for an 877 series.

Once again, trying to prove some kind of point incorrectly and doing so by using a completely different denomination from the coin posted by the OP. Smh.

[EagleRJO]

Hmmm, I guess in bowling you use "doubling strike" for consecutive strikes or "double strike" for pins that may move around when they are struck, like dies sometimes move when a coin is struck.  That's why bowlers who have been in tournaments might confuse double strike with strike doubling, which I think should be "machine doubling" anyway.

We all make mistakes occasionally, and not long ago I remember posting the completely wrong coin.  But I owned the mistake while correcting that, instead of making useless excuses related to some other hobby I had.  This does sound like just another excuse for getting it wrong again, and maybe he should just lurk and learn more for a while.

[VKurtB]

I'm still looking for a suitable explanation why so many are captivated by "doubling". It's not what this hobby is generally about.
