I think the herd mentality often feeds upon itself. When collectors hear that an area is hot, and that area has always been on their want list, they will sometimes try to buy that card out of fear that it may continue to go up beyond their price range. So they want to get a card into their collection while they can (they believe). I think this is what is happening to the Mantles and the key HOF rookies. The high end can sometimes drag the mid-range grades up also to a degree because of this.
