1966 Topps Batman Riddler Back #36B

Centering estimate: left border appears noticeably wider than right (roughly 65-70% left / 30-35% right), and top border slightly wider than bottom (approximately 55/45 top-to-bottom) — left/right tilt is the primary concern and would likely push toward OC territory at the stricter end of grading, though not severely miscut. Corners: the four corners appear to show light-to-moderate wear with slight blunting visible especially at the lower-left and upper-right; no sharp 90-degree points are present but rounding is not severe. Surface and gloss appear reasonably intact with no obvious creases, staining, or print snow that dominates; gloss retention looks decent for a 1966 card. Back is not visible so no evaluation of the Riddler puzzle back is possible, and the left/right centering skew widens uncertainty — a strong NM (7) is possible if the back is clean and centering measures better in hand, but EX-MT (6) is the most defensible single estimate given visible corner wear and border asymmetry.
