At age 13 I found a 1936 Lincoln Cent with strong Machine Doubling in change. The 3 was doubled, and with a wide separation. It was a striking error, pun intended. Don't have the coin any more, and this is the one that I most wish I still had. Found another nice example at a show in a dealer's $5 junk box. It was a large cent, 1840-something I think. It had a doubled nose. Wide separation. Striking. Sold it to another dealer about a dozen years later for $50. Now I wish I still had it. Machine Doubling is generally considered to be a minimally valuable error, and examples sell for only a few bucks, at most. Yet, examples of such are actually rarer than die doubling, and some are actually unique. But, it seems that nobody loves them. Pity, I think. |

They get no respect because there are too many of them,they are common. It is a matter of supply and demand. John1  |

It is also a matter of their cause, just some loose bolts in the press allowing some vibration to develop.

 to the CCF! Machine Doubling is damage to the coin. It was a normal strike, but then movement of the die cuts into the devices of the coin after it was struck. It's interesting and sometimes massive, but it is damage and it happens quite often. If MD is collectable or not is up to the collector. If MD is valuable or not is up to the coin market and so far, it's not. ANA ID: 3203813 - CONECA ID: N-5637 Clean a coin that may be worth collecting? Please DON'T! When in doubt, leave it dirty!!

For some coins, Kennedy half comes to mind, it's tougher to find examples without Machine Doubling. Even so, if that doubling is dramatic, easily seen by the unaided eye, and if the coin is MS, I'll save it. |

Sounds like the OP may be describing a double struck coin rather than MD. Perhaps a misunderstanding of die chatter? Edit: to the forum! Glad you're here. "Nummi rari mira sunt, si sumptus ferre potes." - Christophorus filius Scotiae

@Yokozuna, I've seen that argument a lot that "it takes place after the strike, and therefore is not an error," but it is still the die that inflicts the damage. By that narrow definition of "error" die caps and double strikes would also be PMD. I would say that it *is* an error, just an incredibly common and boring one. |

Machine Doubling does get respect when it's unusually severe, as in this 1991 cent. Calling Machine Doubling "damage" is simply a case of adopting Alan Herbert's idiosyncratic decision to declare the minting process finished as soon as the hammer die reaches the lowest point of its downstroke. I and many others adopt a later cutoff point. I consider Machine Doubling a legitimate striking error.

That is a dramatic example Mike! Since we're on the subject and have your attention, how about these?   Edited by USSID18

To CCF! To me, they don't get any respect because they're super common to find. I find them all the time CRH (Coin Roll Hunting). Also, they are often on ebay and other websites being mislabeled as a Doubled Die when they're not. Errers and Varietys.

Great examples of DDD can be found on many early 1980s nickels, an era when the mint worked those dies to death. Mike, with that wide Machine Doubling on Lincoln's profile, why isn't there also much on IGWT? |
