The 2021 Topps Chrome Update Base Set Ryan Mountcastle Xfractor #USC39 is a Baseball card (Xfractor parallel) released in 2021. Ungraded copies carry a market value of about $22.81.
An ungraded copy is worth around $22.81, a PSA 9 around $10.72, a PSA 10 (Gem Mint) around $36.02 and a pristine BGS 10 around $47.00. The gem-mint premium is modest (about 1.6× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
The spread between raw ($22.81) and top-graded ($36.02) 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.
