Nothing you say matters really - the simple fact is the card isnt worth that much!!!
Just in this case, too many nubs with a lot of money failed to collect it and as such all bid rediculous amounts of money to finish off there set. This does not mean the card/s automatically becomes the cost equivellent of what these noobs were silly enough to pay for it.
Otherwise according to people who buy from
gandalfs cart there cards all now are valued at $100 US when you can still buy them for $4 each. But you know - following your reasoning someone paid $100 so it must be worth that much.
