No offense, but the only way to really gauge performance is to look at actual sales, not someone's opinion as to prices. Without knowing what factors were used to calculate the Beckett's prices and how they were weighted, you cannot draw any conclusions. You also have to bear in mind that transactions are all over the place, whereas averages are of necessity somewhere in the middle.
I think the market for vintage cards is more robust, especially over the years since ebay and major auctions every week (it seems), than is reflected in a Becketts.
