The 2021 Bowman Sterling Prospect Autographs Bobby Miller #BSPA-BM is a Baseball card released in 2021. Ungraded copies carry a market value of about $5.48.
An ungraded copy is worth around $5.48, a PSA 9 around $57.00, a PSA 10 (Gem Mint) around $68.00 and a pristine BGS 10 around $88.00. That's roughly a 12× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.
Is it worth grading?
With raw copies near $5.48 and top grades reaching $68.00, grading a sharp copy of this card can clearly pay for itself — the spread comfortably covers a typical ~$25.00 grading fee. The catch: only submit copies with strong centering, clean corners, and unmarked surfaces, because anything below a 9 usually erases the math.
