Sorry these are the best I could come up with, with the equipment I have. The main point is that the ear lobes are different on some than the others. Some have the same ear lobe as the other 1999
State Quarters and other have the ear lobe of the 2000
State Quarters. It dose not seam to be rarer for one than the other just different. I was hopping to get some confirmation.
If you have any of the 1999 D Connecticut Quarters Please look at them and see if you can see the difference. The 1999 Quarters have less of a lower ear lobe and the 2000 Quarters have more of a lower ear lobe.
