The 2018 Finest Base Set Buster Posey Gold Refractor #46 is a Baseball card (Gold Refractor parallel) released in 2018. Ungraded copies carry a market value of about $34.22.
An ungraded copy is worth around $34.22, a PSA 10 (Gem Mint) around $119.99 and a pristine BGS 10 around $156.00. That's roughly a 3.5× 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 $34.22 and top grades reaching $119.99, 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.
