Shaded band is the middle half of live Buy It Now asking prices, weekly 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

1966 TOPPS Batman #21 UNITED UNDERWORLD Catwoman Riddler Jok
Estimated grade: 3 (2–4) · MEDIUM confidence · asking $15.50

Centering estimate: left border appears slightly wider than right (~55/45 L/R), top and bottom borders appear roughly even (~50/50 T/B) — centering is not the primary concern here. Corners are the dominant grade-killer: all four corners show visible rounding and wear, with the lower-left and upper-left appearing most degraded; this is consistent with a VG (3) at best. Surface shows multiple fine creases or handling lines across the image area, most notably a diagonal scratch/crease running through the center-left of the image, and additional stress lines are visible — this pushes the card toward the lower end of the range. Gloss appears significantly reduced across the surface. The card's condition is consistent with a PSA 2-3 range; a PSA 3 (VG) is the most likely outcome given the rounded corners, visible surface creases, and gloss loss, though PSA 2 is possible if the crease depth is worse than the scan reveals.

Estimated grade: 4 (3–5) · MEDIUM confidence · asking $29.99

Centering estimate from photo: left border appears moderately wider than right (roughly 60/40 L/R), top border slightly wider than bottom (roughly 55/45 T/B) — centering is passable but not tight. Corners show visible rounding on at least two corners visible from this angle, consistent with light-to-moderate handling wear. The black borders show some edge wear and the surface exhibits gloss loss in spots, consistent with age; no obvious hard creases are visible in the image though the angled shot limits crease detection. Card appears to fall in the VG-EX to EX range (4–5), but corner rounding and gloss reduction pull it toward the lower end; the single photo from this distance and angle prevents confident separation between a 3 and a 5, so the range is widened accordingly.
