i recently examined a couple rolls of 1957D wheat cents. I believe I have found one RPM, which I will try posting later. however while looking through them, I found many (40+%) had die breaks, usually the 9, 5, in the date, the B in LIBERTY, or some combination of all three, along with some "BIE" breaks. the question is - do these breaks, along with the commonality of the combinations, imply a "late die state", or am I attempting to be too general. in other words, did I just look through a bunch of predominately "late die state 57D's? thanks.
