Index grading notes

Centering estimate: left border appears narrower than right (roughly 60/40 L-R favoring right), top border slightly wider than bottom (approximately 55/45 T-B) — centering is off but not severely so, likely within EX-EX/MT range on that dimension alone. The black and red border frame appears intact with no obvious miscut. Corner detail is partially obscured by the watermark overlay and image resolution, but the visible corners suggest minor rounding consistent with light handling — no sharp razor points are evident, pointing toward EX to EX-MT territory. Gloss appears moderate with some surface wear but no obvious creases are visible from this angle. The COA watermark across the center prevents confident surface assessment, widening the range; a crease hidden beneath could drop this to VG-EX (4) territory.

Centering estimate: left border appears narrower than right (~60/40 L/R), top border appears slightly tighter than bottom (~55/45 T/B) — centering is imperfect but not severely miscut. The image is heavily degraded by what appears to be significant surface crackling, toning, and aged emulsion cracking running across the entire card face, which are consistent with a Venezuela printing on thinner stock that has suffered environmental damage. Corner detail is obscured by the scan/photo quality but visible rounding and general wear suggest VG to VG-EX range at best. The pervasive surface cracking and toning visible across the card would be severe surface flaws in PSA's eyes, likely capping the grade at 3 VG; if any of the crackling represents actual paper/surface breaks rather than scan artifact, the grade could fall to 2. Cannot confirm back condition, corner sharpness, or true gloss level from this image — range is widened accordingly.
