Collector's notes

As a recent release, this card's market is still finding its level — prices move with the player's performance, grading population growth, and overall hobby demand.

Is it worth grading?

With raw copies near $75.76 and top grades reaching $610.00, 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.

Buying & selling tips

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.
