Below grade 10 the guide publishes one estimate across all graders, so these rows are not PSA, BGS, CGC or SGC prices, and a low slabbed grade can sit below a clean raw copy. Grade 10 is estimated per grader.
Each point is the last stored observation that day for this printing, condition, grader, autograph status and source. Gaps mean no observation; guide estimates and asking prices are not completed sales.

SuperCatch Expert Analysis
Market Value Insight
This 2024 Topps Chrome Cosmic Buster Posey card trades at a modest entry-level price point, reflecting its status as a non-premium parallel within a modern base set. While Posey remains a significant figure in Giants history, this specific iteration lacks the scarcity drivers that typically command substantial premiums, keeping it accessible for casual collectors. The current market positioning suggests it serves more as a portfolio filler than a high-value centerpiece.
Rarity Breakdown
The card possesses no special attributes such as serial numbering, short prints, or one-of-one designations, indicating it is likely a standard base or common parallel issue. Consequently, supply is not constrained by unique identifiers or limited edition mechanics, resulting in a relatively abundant presence in the secondary market. This lack of distinct scarcity markers means the card does not benefit from the supply-side volatility that often drives value in higher-tier parallels.
Investment Outlook
As a non-rookie card from a 2024 set, this item lacks the rookie-card premium mechanics that typically drive long-term appreciation in baseball collecting. Demand is primarily driven by general interest in Buster Posey’s tenure with the San Francisco Giants rather than specific collectible features. Investors should view this as a low-risk, low-reward asset suitable for completing base set requirements rather than for capital appreciation.
