The 1988 Topps American Mark McGwire #47 is a Baseball card released in 1988. Ungraded copies carry a market value of about $1.54.

An ungraded copy is worth around $1.54, a PSA 9 around $19.99, a PSA 10 (Gem Mint) around $119.79 and a pristine BGS 10 around $156.00. That's roughly a 78× 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 $1.54 and top grades reaching $119.79, 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.
