Gauging Interest For Graded 1967 Topps Who Am I?

jibbajab12

Just wanting to see what the interest is for 1967 Topps Who Am I? cards that have been graded. I've gotten a nice near set (38 out of 44) of the set and are in rather nice condition. I would say that the grades would range from 6's to 8's, possibly a few 9's. I do have the Ruth, Mantle and Mays (unfortunately no Koufax). All are unscratched and still feature the disguise given to each "mystery" person. Although, a few have some light scratches in the disguise from handling and some gunk on the back from packaging, but that appears mostly standard. I just want to know if anyone would know the interest, or demand, for these cards. Would like to get them graded if the demand would be great enough. Don't have a scanner but could post some photo's if anyone is interested in viewing a few. Thanks for the help.
