I have an old wheat back penny, 1958 D. The coin is rough, but the date is doubled, the rest of it is not. Is this a Double-Die.   |

@jim, first welcome to CCF. Second, it looks to me that rather than having a doubled die, you coin is a very nice example of Machine Doubling. The letters are reduced in thickness and the doubling is step-like. "If you climb a good tree, you get a push."

agree with Spence and also to give you another hint: The MD was North versus South. You can see under the leaps and where the papion (butterfly) it is.

Thank you for your response. Since I am a newbie at this, what is the difference in Machine Doubling and Double-Die? Also, does the Machine Doubling increase the value? |

@jim, there is an excellent glossary here on CCF to help you with definitions. Unfortunately, MD doesn't add numismatic value, but since the cost of ownership is so low, you could keep this cent in a 2x2 as an exemplar.

Machine Doubling is when the press shakes the die and the edges of the die shift and flatten the raised portions of the devices already struck. Each MD is unique but common in that it happens often - some collect really large ones like you have. Double Dies are when the die is first created they squeeze it multiple times, and if its is off center between the two then the die has two images of the devices. Each Double Die is the same and are minted until the die breaks or is retired.

Machine Doubling fine example. Value: Roughly 3 cents (wholesale value of wheaties)

Ok I think I'm understanding md and hub doubling Now. So md is when the press die hits the digit taking some away from the digit in question? Rather hub doubling is a second digit overlaying the first? I'm just trying to understand like he is.
