Thank you. With all the stuff on this site. It can be quite confusing for newbies. Thanks everyone. Glad I was able to get feed back though.

Hi Lelah, I haven't seen your other posts, so I don't know if you got an answer. It isn't a doubled die. What you're seeing there is Die Deterioration Doubling. As a die gets to the later stages of its life, letter can appear doubled towards the rim. |

DDD is often mistaken for die doubling but it's not.

Okay so how can you really tell with double die. I am trying to really see this error. But it's hard

Note how the deterioration is flat looking?  It may look raised. But compared with a doubled die, the devices should be raised as much as the other normal size devices: 1955P-1DO-001:  1972P-1DO-001  Note the differences? |

Stop and focus on the die flow. Does it seem raised or flow towards the rim? Another indicator of Die Deterioration Doubling. Thanks, Doug. |

I'm glad this come up again,As I'm still confused with doubling myself. So if the "doubling" North and South that would indicate a true doubling? But east and west that point towards the rim is MD? Thanks for your response,Sorry about hijacking the thread!

Usually the Die Deterioration is towards the rims. Often the MD can be on the central side of the devices, but not always the case. (there are no rules for MD) The hub doubling creates an extra device that is hubbed on the die. MD is a strike issue. Die Deterioration is die wear issue. So they are all different. Hub doubling can be in different directions as there are 9 classes of doubled dies. Created by hub miss alignments, hub distortion and incorrect hubbing location on the dies better multiple bubbings/snap into the correct position during the hubbing process. This a a deep subject. It will take times to get all the different classes of doubled dies down in your head. But know what could happen, is where you look to find doubled dies. |

The way I look at it, DD - happens at the dies creation. Could be North, South, East or West. MD - happens at the time of the strike. Remember the die is normal. Its is more of a machine operation issue. Again can show in any direction until the problem is noticed and corrected. DDD - happens towards the end of the dies useful life from continual use it wears the die(s) down. It will begin to show the effect on the side of the device(s) in LDS - VLDS. Generally shows up first on the side facing towards the closest rim as the die ages and nears retirement. Thanks, Doug. |

I do appreciate the info! I'm sure it will be some time before I get this down. But I will work at it and learn from every coin I see here and in my personal pursuit of a good DDO / DDR! I'm surprised I found that Lincoln the other day! |
