Where To Look For Varieties On The Single Squeeze Memorial Cents.

Two of my finds are in those photos
Thanks for posting coop,I am sure it will help a lot of members.

That's a lot too remember will have to book mark for sure, thanks coop.

coop- It's here somewhere but I'm obviously overlooking it in your many threads and posting. Is there a one-stop-shop resource, database or website listing (besides the obvious Doubled Dies) the most significant finds with ballpark premiums they may hold?

Most of the single squeeze errors are considered class 9. Some have additional classes added to them as the mimic more than one class. An inverted hubbing, was probably caused by the operator of the hubbing started the process, then backed off and repostioned the setup. Normally the hub process for these is just a single squeeze. One shot and your done. But for some reason it was probably interupted and re-hubbed on the inverted one. Most of the class 9 doubled dies are what they call snap into position hubbing. The hub starts off tilted, and when it starts making contact, then it snaps into the correct position. Leaving a distortion in the central area, that the complete hubbing doesn't remove.
We have seen this years ago where the only part doubled on a doubled die is the eyelid.

How does just one area of the eye area just be affected?

Part II. Die Varieties: Doubled Dies: Class V (Pivoted Hub Doubling) Notice the 1966 cent information:



If this rotation affected the devices like this and slightly changed the eyelid, it give us an idea that may have happened on the 2nd or 3rd hubbing. This created this doubled die without erasing all the rest of the design.
So on the example I posted earlier, the hubbing probably was the first hub of the die. It was out of alignment. So the die was hubbed a couple more times and it removed (they thought) all of the first incorrect hubbing. But the eyelid area was not changed because the hub didn't hub deeper in that area. If was a shallow area that was affected. So the eyelid is left and probably not detected by the mint. So a deep hub in a shallow device area leaves the eyelid still visible.

What is nice here is that not just me, but desire to share what they have learned here. I feel that taking the time to tell what I see, helps others to see it also. So it is a community effort. You have a lot of coin family here.

The 2001-2004 DDR's tend to look like MD, but they enlarge the devices a bit:

The first one does look like MD, but note the lower area hear the floor and the planter area?

Hope this helps a bit more.

Thanks. Very informative. Your great effort is well appreciated.

Going through my image files, I was transferring them to disks. But going through them, I found an image I had forgot about wondering that I even had it. But I edited it to show how much the alignment can be incorrect during the die creation process of the single squeeze dies. So I added the information and decided to add this information to the threads that alreay exist to keep things a little closer at hand and here is the information:
