To all my fellow collectors, I have a PSA 9 (mint) card of Viking's adrian peterson (rookie topps xfactor chrome ...where can I find out what it's worth...beckett list it as a $100.00 card ungraded, so I was wondering where I can find out what this card is worth.

I think its safe to add 25%-50% to the card over $100. I have a beckett from few months ago that had some graded cards priced. And that seemed to be the average rate.
PSA sell for a little lower that BGS for new cards. But if it were vintage or IP autos I would go for PSA.
