The 2017 Topps Heritage Base Set Bryce Harper Throwback #427 is a Baseball card (Throwback parallel) released in 2017. Ungraded copies carry a market value of about $350.00.
An ungraded copy is worth around $350.00, a PSA 10 (Gem Mint) around $588.00 and a pristine BGS 10 around $764.00. The gem-mint premium is modest (about 1.7× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $350.00 and top grades reaching $588.00, grading a sharp copy of this card can clearly pay for itself — the spread comfortably covers a typical ~$25.00 grading fee. The catch: only submit copies with strong centering, clean corners, and unmarked surfaces, because anything below a 9 usually erases the math.
