I recently picked up this 1967 quarter with a nice-sized rolling fold.
What's interesting is that I have a second 1967 quarter struck by a different die pair that has a virtually identical rolling fold. As one would expect, it's in a different position. I have seen at least one other 1967 quarter with a rolling fold of the same size and appearance.
I suspect all three were struck by blanks punched out by the same chipped blanking die.
