I think that as SPP says the populations of high end coins are overstated. I have sent a number of top ICCS MS cents to PCGS. So, for example, the (I think still) solo 1941 MS66 ICCS no longer exists. It is now PCGS. One of the (last time I looked) 3 MS66 1935 cents is also gone. Same with one of the 1938s. Also, many coins in older holders are resubmitted for upgrades. I have done this maybe a dozen times. They were all in MS64 holders and are now in MS65 holders. But the MS64 population is still there.
