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 2018 Topps Heritage card of Zack Greinke sits at the lower end of the market value spectrum, reflecting its status as a non-premium base insert. While Greinke remains a significant figure in MLB history, this specific iteration lacks the scarcity or grading premiums that typically drive higher valuations among serious collectors. It trades as an accessible entry point rather than a centerpiece investment piece.
Rarity Breakdown
The card is identified as a standard base issue within the Heritage set, meaning it does not benefit from serial numbering, short-print mechanics, or parallel variations that artificially constrain supply. Without unique attributes to limit its availability, the supply remains effectively unlimited relative to demand, keeping it in the most common tier of the product. This lack of exclusive features means it does not command a rarity-based premium over other base cards in the same set.
Investment Outlook
As a standard base card from a 2018 release, this item lacks the rookie-card premium or special parallel positioning that typically fuels long-term collector demand. The investment outlook is stable but modest, relying on general nostalgia for the Heritage brand rather than specific scarcity drivers. Collectors are likely to seek this card for set completion rather than as a standalone asset for appreciation.
