Lincoln Cent More Pics Of Die Trails

BJ - what causes the trails?

O'kay, I can be reached by e-mail now. Thanks for straightening it all out.

Population on the 1998 - 27 die is three at this time, however, that is not the best of indicators. I imagine that the number will increase as more people find this anomaly type to be a bit more interesting than previously thought.

How they are formed? I did a 18 page article in ERRORSCOPE on just this subject, but to make things very simple, here is an abbreviated explanation. When the hubbing is completed and the hub begins to lift off the die, the die moves. Since there is still pressure from the hub and its collar, any movement of the die in any direction will cause the high points of the hub to dig into the die face. At this point, the steel in the die is softer than the steel in the hub, so the die will mar and the hub will not. The direction of the trail lines (and also the wavy step trail lines) is directly opposite to the movement of the die over the hub. Of course, trail length and intensity, not taking into consideration the age of the die, depends on the amount of pressure of the hub and its collar and the amount of movement by the die.

Why is it not a doubled die?. There is no design element duplication, it is an extension of the design element. Design extension can happen on a doubled die, even on the same design element. The affect of trails is caused by die movement; a doubled die is caused by a displacement of the hub to the die and does not involve die movement (yes, there is some die movement in the single squeeze hubbing process that does create a doubled die, however, it is not the movement that is creating the anomaly, it is the repositioning of the die to the hub).

I hope that I covered all the questions. I will address the Canadian quarters when I get a better look at them in a few hours. If you do have any more, please fell free to ask.

thanks for your answer. if you find that you have time is there any way you can tell me what those marks are?

lol so possible!

ok I am going to do my best to get them to show up a little better. Hopefully it might make it easier to see what it is, but I cant quite figure out how to crop it to just that part of the coin yet.



Im not sure that worked but I'm going to hit post reply and hope for the best.

The "smoking" antlers might be die wear--not sure.
