1966 OPC Batman Black Bat #15 Batman in Action

Centering estimate: left border appears slightly wider than right (approx 55/45 L/R), top border appears slightly wider than bottom (approx 55/45 T/B) — centering is acceptable and not a significant deduct. Corners: at this photo resolution the corners appear reasonably sharp with possible very light wear on one or two corners, but no obvious rounding is visible — consistent with EX-MT to NM range. Surface: gloss appears present and reasonably intact with no obvious creases, staining, or print defects visible; some minor print grain is normal for this 1966 issue. Edges appear clean without obvious nicks. Back is not visible, limiting confidence; the seller's 'NRMT' claim is plausible but the photo does not rule out light corner or edge wear that could push the grade toward EX-MT (6) rather than NM (7).
