To expand on Conder's comments, when you look at coppercoins for help you'll notice the marker photos listed as EDS (early die stage), MDS (mid die), or LDS (late die). One some cents you see example photos from more that one stage, so you'll want to check all.
I've never understood the different classes listed, can anyone explain them.
