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 1989 Topps Mark Grant card represents an entry-level tier within the broader baseball card market, reflecting its status as a standard base card from a high-volume production era. As a non-premium insert or parallel, it lacks the scarcity drivers that typically command significant premiums, resulting in a value proposition that is accessible to casual collectors. The card's pricing aligns with the general market for common players from this specific vintage, where condition sensitivity plays a larger role than absolute rarity.
Rarity Breakdown
The card possesses no special scarcity attributes, such as serial numbering, short-print status, or parallel coloring, meaning it exists as a standard base issue within the 1989 Topps set. This lack of distinct scarcity mechanics implies that supply is effectively unlimited relative to collector demand, as these cards were produced in vast quantities for mass distribution. Consequently, the item does not benefit from the limited supply dynamics that elevate the value of more exclusive variations.
Investment Outlook
Given the absence of rookie card status or premium parallel designation, this item offers minimal upside as a standalone investment vehicle. Demand is likely driven primarily by nostalgia for the 1989 Topps set or specific team completists rather than broader market speculation. Collectors seeking to acquire this specific card should view it as a low-cost acquisition for set completion rather than an asset with significant appreciation potential.
