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 #37 v3 Showdown on
Estimated grade: 4 (3–5) · LOW confidence · asking $4.00

Centering estimate: left border appears noticeably narrower than right (~60-65% right-heavy), top border slightly wider than bottom, rough L/R ratio approximately 60/40 to 65/35 — borderline but not catastrophic. Corners show visible rounding on at least the visible corners, consistent with VG-EX to EX range. Surface shows moderate gloss loss and some toning typical of OPC stock, with possible light handling wear; no creases are clearly visible but the image resolution and color fading make it difficult to rule out light surface creases. The photo quality and warm color cast obscure fine detail on edges and corners, warranting a widened range — back is not visible so Riddler-back claim cannot be visually confirmed, but the front image matches the listed card.

Batman Riddler Back 1966 O-Pee-Chee: Card #37 v2 Showdown on
Estimated grade: 4 (3–5) · MEDIUM confidence · asking $4.50

Centering estimate: left border appears noticeably narrower than right (approximately 70/30 L/R), top and bottom borders look more balanced at roughly 55/45 T/B — centering is off but not miscut territory. Corners show visible rounding/wear on at least two corners visible in the scan, consistent with a VG-EX to EX range. Surface gloss appears reduced with some scattered wear but no obvious hard creases are detectable from this image; however the photo resolution limits confident crease assessment. As an OPC printing, paper stock and print characteristics differ slightly from Topps USA issues; the card shows typical vintage handling wear placing it most likely in the VG-EX (4) range, with EX (5) possible if corners are softer than they appear and no hidden creases exist on the back.
