When Are Doubled Die Coins Not Struck Doubled Die?

It kinda makes me wonder if you are describing Machine Doubling or Die Deterioration Doubling where both have that steplike look to it.

I'm well aware that not all are struck twice and no I'm sorry but (II) isn't md
I'm speaking of almost complete separation
When I say a mirror image I'm speaking a mirror image only difference is instead of the devices being same height one sits lower but can at some times have sections or pieces of one or more show as equal where the majority as stated above sits lower

OK, when you say 'mirror image' are the letters and numbers appear to be backwards?

Would your answer constitute a double negative, thus making it a positive answer?

LOL Dearborn. Doubled die coins are not struck doubled die when the die itself is not doubled.

Thank you all for participating I will try and address all. Ok so by mirror what I'm trying to describe is if you were to take a picture of a coin such as I'm describing and the well known example superimposed them you would find they align in every way so in answer to your question no the devices are not a reverse image. Apologies for the wording of the title but as you can see the question in its self is difficult to describe. Ok so who is to say the die isn't doubled because this is the ultimate question. Let's look at it this way couldn't the die be doubled and also be a light strike from adjustment, couldn't it also be a doubled die while being greedy packed therefore showing a faint second device? So the other answer is not "never" making this positively a difficult question

there's 8 classes of doubled dies, 9 if you include hybrid doubled dies which involve two classes of doubled dies on the same die.

There isn't any real doubled die outside of these classes of doubled dies, because then it's not a doubled die. it DDD or MD, or other forms of Mechanical Doubling or even a second strike.

the reason I say the question could be worded better is because people have spent lifetimes researching doubled dies, how they happen, what is a doubled die, what each type looks like..... and what is machine caused during striking, and how to tell the class of doubling it is. If you can't nail down what class it is, then it's likely NOT a doubled die.

Who is to say the die isn't doubled? the researchers that have spent their lives researching doubled dies, that's who.

yes, you can have a doubled die WITH a light strike from a power surge, or adjustment strikes. Yes you can have a doubled die with MD or DDD also present. You can have a doubled die Greaser. That would be a doubled die with another type of issue also.
Still it's either a doubled die where the doubling is on the die itself, that falls into one or more of the classes of doubling, or it's just not a doubled die.

Sorry Dearborn, I thought you were being humorous.
