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 1987 Topps Chris Bosio card sits at a baseline entry-level price tier, reflecting its status as a standard base card from a high-volume print run. While Bosio was a significant contributor for the Milwaukee Brewers during this era, the lack of special attributes keeps this item well below premium parallels or insert cards in relative value. It serves as an affordable foundational piece for collectors focusing on Brewers history or 1987 Topps completists rather than a high-value investment asset.
Rarity Breakdown
The card carries no scarcity mechanics such as serial numbering, short-print status, or parallel variations, placing it firmly in the common tier of the set. Its supply is defined by the standard production volume typical of base cards from the late 1980s, meaning availability is high and no limited edition factors constrain the market. Consequently, the card does not benefit from the supply-side scarcity that drives premiums in other segments of the hobby.
Investment Outlook
As a standard base rookie-adjacent card from the mid-1980s, this item appeals primarily to bulk collectors and those building specific team sets rather than speculative investors. Demand is driven by nostalgia for the 1987 Topps set and the Brewers franchise history, but the absence of unique attributes limits its potential for significant appreciation. Collectors should view this as a low-cost acquisition for breadth of collection rather than a vehicle for capital growth.
