The 1975 Fleer Pioneers of Baseball John Glasscock #21 is a Baseball card released in 1975. Ungraded copies carry a market value of about $2.67.
An ungraded copy is worth around $2.67, a PSA 10 (Gem Mint) around $68.58 and a pristine BGS 10 around $89.00. That's roughly a 26× 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 $2.67 and top grades reaching $68.58, 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.
