1966 OPC Batman Black Bat #20 Robin to the Rescue

Centering estimate: left border appears noticeably wider than right (~65/35 L/R), top and bottom borders look reasonably even (~55/45 T/B) - centering is off horizontally but not catastrophically so. Corners appear to have light rounding at visible edges, consistent with EX-MT to NM range; no sharp razoring evident but no severe wear either. Card surface shows reasonable gloss retention with no obvious creases or staining visible. The card exhibits slight bow/curl which is common for vintage OPC stock and does not affect grade, but back cannot be assessed and corner closeups are unavailable, keeping the range wide from EX to NM.

Centering estimate: left border appears noticeably narrower than right (approximately 70/30 left-to-right), top border slightly narrower than bottom (roughly 55/45 top-to-bottom) — centering is off-center left-right but not catastrophically so, consistent with EX to EX-MT range at best. Corners show light rounding on at least the visible lower-left and lower-right corners, suggesting wear consistent with EX (5) rather than EX-MT (6). Surface gloss appears moderate with some typical vintage print texture and slight toning, but no obvious creases are visible from this angle. Edges look reasonably clean with the typical rough-cut texture normal for OPC/Topps 1966 vintage stock; back cannot be assessed and corner wear is difficult to confirm precisely at this resolution, widening the range accordingly.

Centering estimate: left border appears notably wider than right (roughly 70/30 L-R), top and bottom borders appear closer to 55/45 — the left-right imbalance is the primary centering concern. Corners: the visible corners (especially lower-left) show mild-to-moderate rounding consistent with handling wear, upper corners are harder to assess cleanly due to image angle. Surface: gloss appears present but somewhat muted; no obvious creases are visible, consistent with the seller's 'very nice' claim and no self-disclosed creases. Edges appear intact without significant nicks. The overall presentation suggests an EX range (5) as the most likely grade, with EX-MT (6) possible if corners are sharper than they appear and centering measures better; VG-EX (4) is the floor if corner rounding is more pronounced on closer inspection.
