If they're comparing BCCG to PSA they're not getting it.
But psa 9 Younts while not exactly all that tough (currently 167 of them out there) They do sell for a bit.
Some actual results posted here by PSA
http://www.psacardfacts.com/CardDetail.aspx?item=35512
$428 to $607, the highest one and most recent in 2011.
So if it really should be a 9 they're not all that far off.
Of course, an 8 is just about as nice, and lots cheaper. And an nice "NM" one ungraded would be cheaper still.
