The 1999 Topps Chrome Mark McGwire HR 34 #220 is a Baseball card (HR 34 parallel) released in 1999. Ungraded copies carry a market value of about $4.56.

An ungraded copy is worth around $4.56, a PSA 9 around $79.80, a PSA 10 (Gem Mint) around $127.00 and a pristine BGS 10 around $165.00. That's roughly a 28× 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 $4.56 and top grades reaching $127.00, 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.
