2018 Topps High Tek Base Set Bryce Harper Rainbow Foil Black #HT-BH value & prices

The 2018 Topps High Tek Base Set Bryce Harper Rainbow Foil Black #HT-BH is a Baseball card (Rainbow Foil Black parallel) released in 2018. Ungraded copies carry a market value of about $20.10.

An ungraded copy is worth around $20.10, a PSA 9 around $32.50, a PSA 10 (Gem Mint) around $105.05 and a pristine BGS 10 around $137.00. That's roughly a 5.2× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.

Is it worth grading?

With raw copies near $20.10 and top grades reaching $105.05, 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.
