Is my 1986 Fleer Jordan worth grading?
Based on your AI grade of 8.5 and current PSA 8 comps at $4,200, grading fees would run ~$150 and could add $800–1,200 in value. Worth it if centering holds up under closer inspection.
What's the PSA 9 population look like?
PSA 9 pop is around 3,200 — fairly common for this issue. That's why the PSA 10 premium is so large (~6×). A PSA 9 won't move the needle much over raw.
