The 2020 Bowman Chrome Buster Posey Gold Refractor #21 is a Baseball card (Gold Refractor parallel) released in 2020. Ungraded copies carry a market value of about $34.88.
An ungraded copy is worth around $34.88, a PSA 9 around $102.50, a PSA 10 (Gem Mint) around $103.50 and a pristine BGS 10 around $135.00. The gem-mint premium is modest (about 3.0× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $34.88 and top grades reaching $103.50, 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.
