The 1999 Bowman's Best Mark McGwire Refractor #70 is a Baseball card (Refractor parallel) released in 1999. Ungraded copies carry a market value of about $66.42.
An ungraded copy is worth around $66.42, a PSA 9 around $80.00, a PSA 10 (Gem Mint) around $107.07 and a pristine BGS 10 around $139.00. 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 ($66.42) and top-graded ($107.07) 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.
