That's a die gouge. It's physically impossible for the rim to be doubled. The rims aren't on the dies, they're on the planchets themselves. Therefor as it is a physical element it cannot be doubled. The reason it's doubling on the columns is that is where and how single squeeze doubled dies form.

Yes that could be a die gouge. I agree with @gc.

Maybe I'm not following you, Grapecollects, but the rim is absolutely a die feature. While it's true that the planchets are put through a machine that flares the rim before striking, the rim of the coin is created by the gutter of the die. If the rims weren't part of the die, you wouldn't get rim Cuds. Edited by SamCoin

What I meant to convey is that since the rims are a part of the die that is not a result of the hubbing process and pre-exists the hubbing process that it cannot be doubled. |

It maybe a die dent. (someone dropped the die on a hard surface or onto another die)

Thanks Guys. Its just interesting how it looks like the mark of a Doubled pillar. Perhaps the Double Pillar is not really a Double Pillar. Could it be a Damaged Die as this is HUMMMMM.  |

How would a reverse Column (pillar) get hubbed onto an obverse die?
But if this same feature appeared on a reverse near the rim I don't think it would be considered a column if it was by itself. Doubling near the perimeter usually (always?) has additional doubling around the perimeter.
Aren't the working hubs slightly convex in shape? As I understand the process with Single Squeeze hubbing, for doubling of a single device (ear, eyelid, column, etc), the doubling is limited to the central area of the die because of the convex nature of the surface of the working hub. With the single squeeze, the prevailing thought is that the techinician working the hubbing process may start the process, but then may have to separate them for some reason before the process is complete. This may leave part of a secondary and centrally located device on the working die.
I hope others will correct my understanding of the process if it isn't correct.

The bar stock tip that creates the hubs and dies are convex:  The Hubs are positives, like the coins.     The dies are negatives to create the Hubs and coins.  Note the shape of the die. You can see the lugs that are on the created blank, but still needs to be tapered for a die, removing the lugs:  Check for exact size before they are used:  Put away for usuage:  Different setups, for different uses.  (The descriptions on these maybe backwards now that I look at them?) |

Petespockets55 I should have said it different. I was trying to say the mark on the obverse of this coin looks like the mark on the Reverse of a coin with a Doubled column. I was kinda thinking if it looks the same could the doubling on the reverse just Die Damage instead of Doubled Die Column?

Also, the overwhelming majority of them being confined to the one column bay is too coincidental to be random damage. I agree with Coop that this is likely a die dent. The die was dropped or hit against something, causing a part of the die's edge next to the L to be dented or flattened. What is more likely: That this one random dent looks just happens to look like a minor featureless doubled column? Or the hundreds of documented doubled columns are all coincidental damage?
