The 2017 Bowman's Best of Autograph Ryan Mountcastle Refractor #B17-RM is a Baseball card (Refractor parallel) released in 2017. Ungraded copies carry a market value of about $4.20.

An ungraded copy is worth around $4.20, a PSA 10 (Gem Mint) around $115.01 and a pristine BGS 10 around $150.00. That's roughly a 27× 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 $4.20 and top grades reaching $115.01, 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.
