1966 OPC Batman Red Bat #20A Surfing Sleuths

Centering estimate: left border ~10%, right border ~15%, top border ~12%, bottom border ~13% — approximately 60/40 L/R and 52/48 T/B, reasonably well centered overall. Corners appear lightly worn with very slight rounding visible at all four tips, consistent with EX-MT to NM range; no corner is sharply crisp but none shows heavy rounding either. Surface shows good gloss retention with no obvious creases, scratches, or staining visible; print quality looks clean with no notable snow or color defects. Back is not visible so hidden flaws (creases, stains, write-on) cannot be ruled out, and corner wear is difficult to assess precisely without macro shots, warranting a widened range of 5–7.

Centering estimate: left border appears narrower than right (approximately 70/30 L/R), top border slightly narrower than bottom (roughly 60/40 T/B) — moderate left-right miscentering but within EX-MT range. Corners appear reasonably sharp with only very light wear visible at the top-right corner; the remaining three corners look clean but cannot be fully confirmed at this resolution. Surface gloss appears intact with no obvious creases, staining, or print defects visible; some minor print grain consistent with vintage OPC stock is noted. The white border shows light toning typical of the era and does not significantly penalize the grade; a back inspection and corner macro shots would be needed to refine the estimate further.
