Shaded band is the middle half of live Buy It Now asking prices, daily intervals; the line is the median. Auctions are excluded - a climbing bid is not an asking price. The scale follows the asking prices, so a sale well outside them is pinned to the edge rather than flattening the band.middle halfconfirmed salebest offer, at its cap

Centering estimate: left border appears notably wider than right (~70/30 left-to-right), top and bottom borders look closer to 55/45 — the horizontal off-center is the primary centering concern. All four corners show visible rounding and wear, consistent with a VG card; no corner is sharp. The black border shows edge wear and chipping in multiple spots, particularly along the bottom and left edges. Surface gloss appears largely gone with general toning across the image area; no obvious hard crease is visible in this photo, but the overall wear pattern and loss of gloss push this firmly into the VG range. The back is not visible so Riddler-back confirmation cannot be made from this image alone, though the seller's description is consistent with the card design shown.
