Shaded band is the middle half of live Buy It Now asking prices, 6-hour 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

Batman Riddler Back 1966 O-Pee-Chee: Card #31 v2 Bat on a Bu
Estimated grade: 4 (3–5) · MEDIUM confidence · asking $5.00

Centering estimate: left border appears notably wider than right (roughly 65/35 L/R), top border slightly wider than bottom (approximately 55/45 T/B), so horizontal centering is the primary concern. Corners show visible rounding on at least two corners visible in the scan, consistent with moderate handling wear. The surface shows some color fading and print grain typical of OPC issues, with modest gloss loss across the face. No obvious hard creases are visible from this scan, but the image resolution limits confidence in ruling out light surface creases; the worn corners and off-centering point to a VG-EX (4) estimate, with EX (5) possible if corners are better than they appear and no creases exist on the reverse.

Batman Riddler Back 1966 O-Pee-Chee: Card #31 v1 Bat on a Bu
Estimated grade: 4 (3–5) · LOW confidence · asking $5.50

Centering estimate: left border appears noticeably wider than right (roughly 70/30 L/R), top and bottom borders appear more balanced at approximately 55/45 T/B - centering is off but not catastrophically so. Corners are difficult to assess precisely at this resolution but appear to show some rounding or light wear on at least two corners, consistent with a VG-EX to EX range. Surface shows some gloss loss and the image presents with the typical OPC vintage color saturation fading; no obvious hard creases are visible but the photo resolution prevents a confident ruling-out of light surface creases. The small card format and fair image quality create meaningful uncertainty - a full grade swing in either direction is plausible pending back inspection and corner close-ups.
