peter chaoJeff,
Your (accurate usage, explained to me by Barry and Jeff L.) comment reflects a real world example of my theory. The registry guys are investors in a sense, they are trying to complete their sets for resale down the road. When the prices start dropping the question becomes whether there is a sufficient group of hardcore collectors to pick up the slack.
For the '33 Goudey cards there's a heck of a large collector base, however, they are collectors and may not care to pay significant premiums for PSA 8, unless it's Benny Bengough perhaps.
So it's quite possible for there to be significant drop for high-end Goudey commons because the collector base to stop the fall may not be there.
