The 2020 Bowman Sterling Prospect Autographs Matt Wallner Wave Refractor #MW is a Baseball card (Wave Refractor parallel) released in 2020. Ungraded copies carry a market value of about $11.80.
An ungraded copy is worth around $11.80, a PSA 10 (Gem Mint) around $15.50 and a pristine BGS 10 around $20.00. The gem-mint premium is modest (about 1.3× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
The spread between raw ($11.80) and top-graded ($15.50) 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.
