I tend to be in agreement, even though this is near to the core of my collection. Also, there seems to be very little demand, even for superior specimens. I have a couple of 3ds of this vintage that also are superior mint state examples, not far in quality from the proofs that I have.
That having been said, there are some very, very nice proofs out there that are unmistakably of that quality. I think my main issue is rather with the Wreath crowns wherein the TPGs have certified FAR too many coins as proofs that are not.
