I've tried to show this a few times to explain the difference between the
DDR's and normal coins with these shields. Where it's a different type of doubling (Class 9), it's not what we are used to seeing with other types of doubling, where you have separation and possibly notching. Look at gigi's find and notice how the vertical is thicker and the horizontal is thinner, this creates a distortion of sorts. Now if you look at Rob's example and the normal example, you will see that it is consistent in all directions, no distortion. That is why I think that Rob's is just from deterioration, also, I have noticed that the Denver coins have a thicker font to begin with. See what you think about the pics below. Here is a link to gigi2110's thread. LINK
