Questions about selling a postwar collection

[swarmee]

Since you posted them, here's my opinions of the cards you've uploaded:
Gaylord Perry probably a 5 due to corner wear.
Frank Robinson maybe a 6.5
Phil Rizzuto also around 6-6.5; bottom right corner keeps it from a 7
Shantz is around a 7.
7th series checklist could be a 7 with slight corner wear on two corners
Green tint Babe Ruth probably an 8(OffCenter) or a 7 straight. Ask for no qualifiers if you don't want it to be OC.
Regular Ruth probably a 7 due to bottom border wear.
Buhl would also get OC since it's 20/80 left to right, or even worse if they measure to the curve of the P for pitcher.
Top right and middle left Witt look the best for centering; both are off top/bottom, but normally collectors don't mind that as much as left/right.
Top right and bottom Landrum are the only ones worth grading when looking at centering. Only the bottom Foytack would be worth grading due to centering.

Hope that helps.
