The 1977 O-Pee-Chee Inge Hammarstrom #320 is a Hockey card released in 1977. Ungraded copies carry a market value of about $1.55.
An ungraded copy is worth around $1.55, a PSA 9 around $21.47, a PSA 10 (Gem Mint) around $89.00 and a pristine BGS 10 around $116.00. That's roughly a 57× 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 $1.55 and top grades reaching $89.00, 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.
