Correct. I refer to it as "Machine Doubling." Because it is caused by a machine. The die was normal and altered post strike. (If the die was a doubled die, it could affect it with Machine Doubling) So you can have Machine Doubling on a "Doubled Die," but Machine Doubling never creates a Doubled Die. Only a Doubled Die can create a double doubled die coin. (Die issue, rather than a machine issue, is the difference) Edited by coop

Not tough at all, This shows classic MD. Quote:
Double Dies vs Machine/Mechanical Doubling is in that 10,000,000 coins? Is it something like 0.003% or 0.7% or 5%? Putting a number on DD vs MD is next to impossible, however you will find that almost every coin will have MD (with exception of coins struck with new dies) as the die wears out and the machine loosens up after the initial set-up the MD gets worse. |

Machine doubling, yes. Machine Doubling is an 'in the striking chamber' occurrence--purely mechanical. Doubled dies are the result of doubling found on the die itself before a mint run is executed. |

Oh, so a true Double Die coin is caused by the Die being damaged? So a coin could have both Double Die and Machine Doubling at the same time? This hobby just got more difficult, lol. |

A DD is a result of an improperly made die, not a damaged die. And MD can occur with a new or old die.

Are coins with dramatic Machine Doubling worth more than face value. On a scale of 1 to 10, 10 being the most dramatic Machine Doubling, where does my 1987 dime fall? |

Using your scale, your dime would rate as a #1 or a #2. The dramatic examples are when you can see the flaw without optical aid. In general, coins with Machine Doubling are not worth a premium. Do not confuse Machine Doubling with a true doubled die. One is an error (the doubled die) and the other is not.  |
