The 1980 Topps Duane Kuiper #429 is a Baseball card released in 1980. Ungraded copies carry a market value of about $1.74.
An ungraded copy is worth around $1.74, a PSA 9 around $22.44, a PSA 10 (Gem Mint) around $43.97 and a pristine BGS 10 around $57.00. That's roughly a 25× 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 ($1.74) and top-graded ($43.97) 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.
