I continue to try to educate myself on Cuds, Die Breaks, and other imperfections. The pics contained here are of a 2004 P Roosevelt dime. Obverse and reverse are included. The two pics taken with my microscope show a cud(?) on Roosevelts ear and 2 (cuds?) in the upper part of his hair. Exactly what would you consider them to be? Cuds, die deterioration, or something else?
A die clash is when two dies strike (or clash) together without a planchet in between. Any future coins struck with those dies bear evidence of the clash. Clash marks are almost always seen the the fields of the coin since they're generally the highest points of the die. Die breaks, cracks and chips are all caused by die deterioration. A cud is a die break that involves the rim. Your dime has a combination of die chips and cracks.
