I would need to see examples of what you have found. There can be MD examples even on doubled die dies. So the ones listed on coppercoins and the Wexler site are examples of the 'known' ones. So seeing an image will help use see what you can found for sure.

While you posted your coins, I was just answering. Those are examples of machine damage after the strike. Note how they are flat on the side you are noticing. Also the color is all the same in those areas. because they are flat and not fading in light if they were the normal contour.
