The 2017 Finest Base Set Buster Posey Gold Refractor #83 is a Baseball card (Gold Refractor parallel) released in 2017. Ungraded copies carry a market value of about $18.50.
An ungraded copy is worth around $18.50, a PSA 10 (Gem Mint) around $110.39 and a pristine BGS 10 around $144.00. That's roughly a 6.0× 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 $18.50 and top grades reaching $110.39, 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.
