About this card's market
Cards from this era were printed in enormous quantities during the hobby's boom years, so raw copies are plentiful — but strict grading separates the true gems from the masses, and top grades remain hard to pull off.
The basketball card market rewards star power — top players' cards consistently outperform the broader market.
Is it worth grading?
With raw copies near $9.99 and top grades reaching $225.00, 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.
PSA remains the most liquid grading label in the hobby, while BGS (with its Black Label 10) and modern entrants CGC and SGC have growing followings — the table above shows how each label prices for this card.
How to buy this card
The fastest way to gauge the real market for this card is to scan the live eBay listings above: look at the spread between auction and Buy-It-Now prices, and check sold history before paying top dollar.
Selling? List smart: photograph corners and surface clearly, state the condition honestly, and price against the grade table above. Or scan it into your Ripbin locker and let bids come to you.
