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 base card from the 2020 Topps Opening Day set represents a standard entry point for Bryce Harper collectors, trading at a modest premium relative to older base issues due to his continued relevance with the Philadelphia Phillies. While it lacks the scarcity drivers of parallels or inserts, the consistent market activity for Harper ensures it remains a liquid asset within the broader baseball market. Its value is anchored by the player's star power rather than any unique physical attributes of the card itself.
Rarity Breakdown
As a base card with no noted special attributes, this item does not possess inherent scarcity mechanics such as serial numbering, short-print designations, or parallel variants. It is produced in the highest volume tier of the set, meaning supply is effectively unlimited compared to the limited-edition subsets within the same release. Consequently, rarity plays no role in its valuation, distinguishing it sharply from the more exclusive pieces of the 2020 Topps Opening Day collection.
Investment Outlook
The investment potential for this specific card is limited by its status as a non-premium parallel in a major brand release, offering stability rather than significant upside. Collector demand is driven primarily by Harper's enduring presence in the MLB and his association with the Philadelphia Phillies, ensuring steady interest in his memorabilia. Investors should view this item as a foundational holding for a general Harper collection rather than a speculative asset capable of outsized returns.
