The 2018 Bowman Chrome Prospects Pete Alonso Purple Refractor #BCP137 is a Baseball card (Purple Refractor parallel) released in 2018. Ungraded copies carry a market value of about $18.75.
An ungraded copy is worth around $18.75, a PSA 9 around $22.00, a PSA 10 (Gem Mint) around $26.00 and a pristine BGS 10 around $34.00. The gem-mint premium is modest (about 1.4× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
The spread between raw ($18.75) and top-graded ($26.00) 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.
