Forum - Am I out of touch with today's collectors?

[3arod13]

I realize this isn't a game used matter, however, the autograph forum just doesn't receive as much traffic, but this does relate in some ways to the many discussions we have in this forum about collecting:

I do realize that collectors collect what they want and are willing to pay crazy prices for whatever they want. Hoever, this has has me stumped:
Recently, a 2006 Ultimate Buy Back 1989 Upper Deck #1 Ken Griffey JR. autographed card sold on ebay for $810. As you can see, the card isn't graded, card is off center, and corners aren't that sharp.

I recenlty listed my 1989 Upper Deck #1 Ken Griffey JR. Rookie Card, autographed and graded PSA 9, which sold for $177.50.

Am I missing something? I understand that today's collectors want autographed insert cards. With both cards being the same, wouldn't you want the PSA 9 graded autographed card vice an autographed insert card which isn't in as nice condition?

Thanks in advance for you opinion.
