Index grading notes

Centering estimate: left border appears narrower than right (roughly 60/40 L/R favoring right), top border slightly wider than bottom (roughly 55/45 T/B) — centering is off but not severely so, likely in the 80/20 range on the tighter axis. All four corners show visible rounding/softening, most notably the bottom-left and top-right corners, consistent with a VG-EX range card. Edges appear somewhat rough but this is typical of OPC cuts and should not be heavily penalized. Surface gloss appears partially present with some loss visible, and the white border shows mild toning/aging consistent with a 1966 vintage card. No obvious creases are visible in this scan, though the scan quality and central watermark obscure the surface detail enough to prevent ruling one out entirely, which is why the floor is held at 3.

Centering estimate: left border appears notably wider than right (roughly 60-65% left bias), top border slightly wider than bottom — left/right approximately 65/35, top/bottom approximately 55/45, so centering is an issue but not catastrophic miscut territory. Corners show visible rounding on at least two corners visible from this angle (top-left and bottom-right appear softened), consistent with VG-EX to EX range. Surface shows some light soiling or toning, and there is a faint horizontal mark near the lower-left quadrant that may be a very light surface crease or print artifact — if a true crease, grade pulls toward VG (3). Gloss appears partially retained but not sharp, with some wear to the card face. The watermark overlay obscures fine surface detail in the center, preventing a confident assessment of print snow or deeper surface flaws; range widened accordingly.
