The 2023-24 SkyBox Metal Universe 2008-09 Rookie Retros Matthew Knies #R-6 is a Hockey card. Ungraded copies carry a market value of about $2.77.
An ungraded copy is worth around $2.77, a PSA 9 around $13.80, a PSA 10 (Gem Mint) around $39.03 and a pristine BGS 10 around $51.00. That's roughly a 14× 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 ($2.77) and top-graded ($39.03) 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.
