The 1999 Upper Deck Wonder Years Greg Maddux #WY17 is a Baseball card released in 1999. Ungraded copies carry a market value of about $1.87.
An ungraded copy is worth around $1.87, a PSA 9 around $11.50, a PSA 10 (Gem Mint) around $39.99 and a pristine BGS 10 around $52.00. That's roughly a 21× 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 ($1.87) and top-graded ($39.99) 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.
