Do I understand right that die doubling on incuse devices is impossible by definition? And what about device-over-device, as with mint marks? Can that happen to incuse devices in any way? Edited by Kawliga

I think I understand what you mean but I'm not entirely for sure. Can you please give me an example of what the incuse devices on a coin are? I'm quite interested in this and have never heard of such a thing.
I'm sure the experts will chime in soon.

Incuse devices are the ones pushed in rather than relief (sticking out). The near-edge lettering on the ATB Quarters is incuse, for example. |

Depends on what coins you are talking about. On the ATB Quarters the devices on the outside edge of the reverses, the coins that show doubling on these devices are Machine Doubling. 70% percent show mild to strong doubling.  On the shield cents, the incuse devices on the EPU when they have Machine Doubling on them, they are also enlarged.  On hub doubled EPUs the hub doubling is showing reduction in size on the doubled dies:    Also on the VDB, which have incuse devices, when they are showing doubling, it is Machine Doubling because it is enlarged:  So because raised devices show enlarged devices on these devices, and reduction of the devices on the machine doubled examples. Just the opposite on incuse devices. Enlarged devices for MD, reduced devices on incuse devices. Just the opposite happens. |

Ah okay that makes sense! And so actual (not machine) doubling IS possible, but it just looks the opposite of relief doubling. So, here's why I ask. I just got a brand new 2019 'River of No Return' quarter, and the E in EPU has what appears to be doubling. I have seen plenty of the Machine Doubling like in those photos, and even more "convincing" than those, but I knew better. This one is different. I wouldn't blink if it weren't for two things: 1. It's not straight-line with that dragged look, but ROTATED, with distinct separation. May even be a device other than the letter 'E', hard to tell, it really needs a microscope exam I think. 2. It's such a new release coin, who knows, right? I took the best photos I could just using the visual impairment magnification feature on my iPhone; I don't have a working microscope camera. And I'm at the mercy of my phone to decide when to update my laptop, then I will upload the photos here. |

My experience fails me, as I can't really judge the coin from just description, so before I am able to judge, I will need the photos.
Take your time, we'll all be here once you're ready to upload them.

There have been a couple of DDO's on the Motto on the States quarters and the ATB Quarters. But they seem to be rare. More of a doubled die on the ears most of the time:  The one on the States Series is a proof PS quarter.  I feel this one was hubbed slightly, then back off and hubbed again. (which is not supposed to happen) But this is the only one I've seen that looks that strong on the reverse die. |

Always best to know what your looking for. Also knowing why it is/isn't a collectible.
