Or it could be a later die state and the markers hadn't formed on the die when your coin was struck. One thing that doesn't change is die damage like die cracks. If your coin is a match, and doesn't have the crack, it is a previous die strike. If the die crack/s look larger/longer or multiple, that is a clue that was struck later than your example. But lets say you have a die crack and the listed one has a die crack, but on a different area of the device. Chances are they are not from the same die pair. (Trying to help you to think outside the box a little) Some times they appear close, but not a match and they are not from the same die. Of if you have doubling that is extra, then it maybe not from the same die, but a new/different die. So a lot of investigation can go on matching dies. Some years have as many as 176 different
DDR's for them. So I try to match up three markers that appear on a coin to match a know die number, before I'm real sure of a match , or not a match.
