Need current "book values" for 3 PSA graded cards
 

I am looking for the current book value (not an online auction survey reference) for 4 of my graded cards:
(not sure where to look for this information online since I'm not a registered PSA member or anything like that;I'm simply cataloguing my collection).
I would prefer Krausse prices,but Becketts is OK,too.
I just need the current book value for these:

1960 Topps # 73 Bob Gibson NM-M PSA 8
1961 Golden Press # 9 Joe D ExM PSA 6
1985 Topps # 401 Mark McGwire RC NM-M PSA 8 (centered)
1987 Donruss Rookies # 52 Greg Maddux RC PSA Mint-9 (centered)

Thank you for the information, or feel free to send me a (free) link to where I can FIND this information.

Current SMR lists the prices, in order, at $160, $20, $17, and $12.

Exactly what I was looking for. THank you!
