The 1980 O-Pee-Chee Blake Dunlop #370 is a Hockey card released in 1980. Ungraded copies carry a market value of about $1.93.

An ungraded copy is worth around $1.93, a PSA 9 around $26.00, a PSA 10 (Gem Mint) around $255.00 and a pristine BGS 10 around $332.00. That's roughly a 132× 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 $1.93 and top grades reaching $255.00, 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.
