Is the baseball card market a "perfect" market? The Demise of the "price guide"

[arc2q]

I agree they are growing in obsolescene from the days when a price guide was the primary source of such information. It seems almost comical when you see auction descriptions say something like, "The card is worth $1500." It is worth what it sells for at auction -- something you will find out conclusively in 6d23h. Auctions are not a perfect market but they are far more reliable as a price determination than a price guide which may be based on total speculation.

I wonder why price guides like SMR have to be published every month? They seem to be using up a lot of content space for reprinting the same list (which is dubious to begin with) each month -- and they never change. They only list certain sets and then refer you online for other sets. Why not vary which sets are included in the price guide each month?

The thing that bugs me in price guides are the modern card listings (I have said this before so it is almost like my mantra). They throw around values that you know are totally made up and it is what leads to ridiculous bubbles. How does anyone know what the limited edition, signed, orange chrome, refractor card of the next supposed superstar rookie would really be worth when it has only been printed and available for two weeks and has never properly been exposed to the market? Yet they'll stick some number like $10000 next to it. Who would pay $10000 for a card printed last week of a player who probably has 3,000,000 different cards in print anyway?
