The 2025-26 Upper Deck Black Diamond Rookie Gems Signatures Matthew Robertson #RGS-MR is a Hockey card. Ungraded copies carry a market value of about $5.38.
An ungraded copy is worth around $5.38, a PSA 9 around $18.02, a PSA 10 (Gem Mint) around $51.85 and a pristine BGS 10 around $67.00. That's roughly a 9.6× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.
