What do these images have in common?
First off, they are all 1993 cents.
I've mentioned about the look at the centers of the devices and not the edges of devices to determine if it is
Machine Doubling or a doubled die. But what do all of these images have in common? They are all examples of
Machine Doubling. Note the overall size of the devices are the same, except for the second example.
But note the second image. That devices shows smaller devices. Well that die was polished it the wider part of the devices went away as the fields were reduced. There was an issue they want to remove on the die. Possible die clash, or another die event that affected need removing something undesirable.
On the third image, the MD affects the centers of the devices. On might think; "This is a doubled die." But note the devices are a same as the other images. (except #2) The machine must of had a strong bounce to hit the devices like that. So one may have submitted it for grading and was probably let down when it was considered normal. But what told me that is was MD and not a doubled die? This. The size of he devices were not affected. Thus I thought others might want to add this to there mental library when searching for doubled dies. If the devices are not enlarged, it isn't a doubled die. The MD on the centers of the devices are distracting, but the devices were not enlarged.
Another reason I wanted to get four images was because the dies that struck these coins were all 4 different die states. Seeing what I see helps to show what I see when I look at a coin. Most would probably no notice these things as they are common events. But if the person who submitted that coin here before having it graded, could have saved himself some money. I hope you enjoyed this thread.
