Do VCP and CardTarget show a better picture than POP reports?

As far as advertising, i know some auction houses just add a disclaimer saying PSA only recently included the back info. I would list it as 1 of 3 known to be graded when doing the listing because there really is no way to know otherwise. Even if you saw a photo of another card graded similarly to yours by PSA, how do you know it wasn't a crossover from what you see on the SGC report? You don't know. Hell, the 2 SGCs could be a crack and resubmit, you don't know. As far as VCP or Cardtarget, I think they do miss a lot of transactions, but they can give you a rough idea on pricing if recent. If it's a rare back, like yours, and it hasn't been sold in the past six months, the values that you see are meaningless since the prices have exploded. I don't think you can gain too much else from their data or lack thereof in the example you've given.
