The 1993 Topps Base Set Garvin Alston / Michael Case Rockies Inaugural #661 is a Baseball card (Rockies Inaugural parallel) released in 1993. Ungraded copies carry a market value of about $0.01.
An ungraded copy is worth around $0.01, a PSA 9 around $10.06, a PSA 10 (Gem Mint) around $30.36 and a pristine BGS 10 around $39.00. That's roughly a 3036× 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 ($0.01) and top-graded ($30.36) 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.
