The 1978 Topps Phil Mankowski #559 is a Baseball card released in 1978. Ungraded copies carry a market value of about $1.15.
An ungraded copy is worth around $1.15, a PSA 9 around $53.94, a PSA 10 (Gem Mint) around $232.91 and a pristine BGS 10 around $303.00. That's roughly a 203× 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 $1.15 and top grades reaching $232.91, 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.
