I come across this every now and then and I think its a finger feeder issue. I seen someone else on another thread and thats what everyone thought it was but just want to make sure. There is die deterioration going on but it goes under the design.
I thought that also but linear blisters will go over the design and from everything I can see this runs under the design.
Every time I see the word Feeder Finger I get hungry.. Why?.. because I love Chicken Fingers and they feed me good! With some BBQ sauce!
Not sure if it was my post but I did find a slew of them in a batch of ten original 1994P LHC rolls. The rolls must have come from the same solid date bank box.
