The 1999 Topps Power Brokers Mark McGwire #PB1 is a Baseball card released in 1999. Ungraded copies carry a market value of about $4.94.
An ungraded copy is worth around $4.94, a PSA 9 around $21.47, a PSA 10 (Gem Mint) around $35.50 and a pristine BGS 10 around $46.00. That's roughly a 7.2× 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?
The spread between raw ($4.94) and top-graded ($35.50) copies is fairly tight, so grading this card only makes financial sense for truly flawless copies — or for collectors who simply prefer slabbed cards for protection and display.
