The 1974 O-Pee-Chee Blake Dunlop #308 is a Hockey card released in 1974. Ungraded copies carry a market value of about $3.00.

An ungraded copy is worth around $3.00, a PSA 9 around $59.91, a PSA 10 (Gem Mint) around $357.16 and a pristine BGS 10 around $464.00. That's roughly a 119× 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 $3.00 and top grades reaching $357.16, 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.
