2006 LMC WDDR-046 (Usually Wouldn't Post A Bar Cent, But This One Is Crazy)

Can yall enlighten me? Are you talking about on column six? The term bar cent is a new one on me.

Yes, as John says, what I'm calling a "bar cent" is just an informal term for single squeeze era (mostly 1997-2008) Memorial cent DDRs that present with extra material on one of the columns in the center bay. The DDRs occur when the hubbing process begins slightly out of alignment and a mint worker stops the press, re-aligns, and starts the hubbing again. Because the unhubbed blanks for the dies are convex, the highest point on the center of the hub is the first thing to "kiss" the die, which leaves just a tiny bit of the design doubled (in this case the memorial columns). Other ultramodern doubled dies that happen this way include doubled earlobes on recent coins, homestead doubled pump/windows, Minnesota extra tree quarters, etc.

@Coop, I believe the ones where the hub snaps into position are believed to cause the smeared devices we see on many modern shield cents, the 2004 FS-801, etc. I think the doubled columns are created when the hub is aligned slightly out of position and the press is stopped and corrected by a mint employee as I described. At least that's how error-ref describes it:

"The second type of die doubling see with the single squeeze hubbing system occurs when the same offset in placement of the hub to the die occurs. Once again, the hubbing is initiated, but stopped by the press operator when the offset is detected. The the hub to die placement is correct and hubbing once again started. This start - stop - start of hubbing leaves Central located design doubling."

@John Kind of a nit-pick, no? People use "extra material" to refer to Cuds even though there is technically no "extra material" there either. In fact, with the exception of rolled thick and wrong planchet errors, there's *never* extra material.

Unless you got a piece of die on the coin:

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:
