The 2021 Topps Tier One Break Out Autographs Michael Brosseau #BOA-MB is a Baseball card released in 2021. Ungraded copies carry a market value of about $10.51.
An ungraded copy is worth around $10.51, a PSA 9 around $21.49, a PSA 10 (Gem Mint) around $46.92 and a pristine BGS 10 around $61.00. That's roughly a 4.5× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.
Is it worth grading?
The spread between raw ($10.51) and top-graded ($46.92) copies is fairly tight, so grading this card only makes financial sense for truly flawless copies — or for collectors who simply prefer slabbed cards for protection and display.
