I'm looking forward to hearing what the experts have to say on this one! I search hundreds of rolls of cents and nickels per week, and I haven't seen that before, either.

I'm no expert but from my past info on dies for plastics it looks like a build up on the plate. Some previous coin, had extra pulled off at the time and then the next stamp pressed it in and down towards the center(Just enough time to cool to create this pattern (lull in production?)). This is normally caused by heat of the press. (too many presses at a time, like a solder Iron)
Again no expert but that's what it looks like to me!!

931 I think maybe right but let wait coppercoin & FIR or Cooper to check out your post. Nice Find!

Actually this is one of the different forms of die wear that happened frequently on earlier zinc Lincolns. The dies acted strangely (as did the planchets) to the new composition, and from 1982-1987 there are a LOT of rather odd looking effects this caused. They started to get it right around 1988, and got rid of almost all the problems by 1992.

What I'm having a hard time understanding, If it is die wear how could it have created the channels above the I and N. The channels are deeper then the field of the coin and in my thinking there would have to be a build up on the die to make those impressions.

Chuck,
I know you are the expert here so I trust your judgement, but I also am confused how die wear could have caused this. To me it appear indented, which would indicate build up. Could some of the lettering have sheared off of another coin and stuck to the die, could this be a struck through error?

Theoretically, as the dies wear, the lettering spreads a little bit.
As the coin is struck the plated layer is actually drawn into the recesses of the die. The metal travels the path of least resistance and is drawn away from the edge and up into the letter causing a depression at the tops of some of the letters.
Thanks,
Bill

To me it looks like the metal had a hard time moving/flowing past that part of the die... Metal flow problem?

Thanks for all the input, There is one more thing I would like to point out that I don't under stand. Pic #4 shows it the best. You can see that the channel on the N goes right into the lip of the rim past were the die should have hit? just trying to under stand this better.
