The 2023 Topps Cosmic Chrome Extraterrestrial Talent Bryce Harper #ET-12 is a Baseball card released in 2023. Ungraded copies carry a market value of about $2.13.
An ungraded copy is worth around $2.13, a PSA 9 around $44.28, a PSA 10 (Gem Mint) around $53.00 and a pristine BGS 10 around $69.00. That's roughly a 25× 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 $2.13 and top grades reaching $53.00, 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.
