Researching the 1989 Topps Griffey Jr #41T-KEN
Match the exact year, set, subject, card number 41T-KEN, parallel, autograph or memorabilia details, and condition before treating a listing as a comparable result. Compare raw cards separately from the same grading company and grade. Recent completed sales are stronger value evidence than active asking prices; remove lots, reprints, and mismatched versions before estimating a range.
