1966 Topps Batman/Riddler Back - #31 - Bat On A Bouy/Batman/
Estimated grade: 3 (2–4) · MEDIUM confidence · asking $5.99

Centering estimate: left border appears notably wider than right (approximately 70/30 left-to-right), top and bottom borders appear closer to 55/45 — off-center but not severely miscut. The card shows significant wear consistent with a VG grade: corners appear rounded on at least two visible corners (lower-left and lower-right show clear rounding), and there is visible surface soiling or staining on the left edge area (a pinkish-red mark is evident mid-left). Gloss appears largely lost across the surface, and there is general toning/aging consistent with a 55+ year old card. No crease is definitively confirmed from this single photo though the surface wear and staining could mask one; the staining alone may push toward the lower end of the range. The rough-cut edges are typical of 1966 Topps Batman and are not penalized.

Estimated grade: 5 (4–6) · LOW confidence · asking $6.95

Centering estimate: left border appears slightly wider than right (~55/45 L/R), top border appears somewhat thicker than bottom (~60/40 T/B) — centering is acceptable for a mid-grade vintage card but not tight enough for NM or better. Corners: at this resolution all four corners appear to show some degree of rounding or softening; no corner looks razor-sharp, consistent with a 4-6 range. Edges appear reasonably intact with no obvious chips or tears visible, though the rough cut typical of 1966 Topps Batman is present. Surface shows no obvious creases from this view, gloss retention is unclear due to the sleeve and modest image resolution — if gloss is largely intact this sits at 5-6, if there is surface wear or a hidden crease it drops to 4. A closer scan of corners and back would be needed to refine this estimate.

1966 Batman Robin Riddler Back #31 BAT ON A BUOY - England
Estimated grade: 4 (3–5) · MEDIUM confidence · asking $7.49

Centering estimate: left border appears notably wider than right border, approximating roughly 70/30 L-R; top and bottom borders look closer to 55/45 T-B - centering is off but not catastrophically so for this series. Corners: all four corners show visible wear and rounding, particularly the lower-left and upper-right which appear more blunted; no corners are sharp. Surface: some gloss loss is evident across the image area and borders; toning on the white/cream borders is present as expected for the vintage. No creases are clearly visible from this photo but the card angle and image resolution make it difficult to rule out light surface creases definitively, which is why the range extends down to 3. Edges appear intact without obvious chips or tears. The card's condition is consistent with a VG-EX (4) grade, though a VG (3) is possible if a crease is present on reverse or front under closer inspection.

1966 Topps Batman Riddler Back #31 Bat on a Buoy
Estimated grade: 5 (4–6) · LOW confidence · asking $9.00

Centering estimate: left border appears slightly wider than right (~55/45 L/R), top border appears modestly wider than bottom (~55/45 T/B) — centering is reasonably acceptable for EX range. The decorative red/black frame border of the Riddler Back series partially obscures the true card borders, making precise centering measurement difficult from this scan. Corner detail is insufficiently resolved at this image scale to confirm sharpness — no obvious severe rounding is visible but no razor corners can be confirmed either. Surface gloss appears present with no obvious creases or staining detected, but the scan's halftone grain prevents confident assessment of print snow, toning, or light surface wear. Range widened due to limited resolution; true grade could fall anywhere from VG-EX (4) to EX-MT (6) depending on corner and edge condition visible only under close inspection.

1966 Batman Riddler Back Card 31 Bat On A Buoy Stunning NRMI
Estimated grade: 6 (5–7) · MEDIUM confidence · asking $25.00

Centering estimate: left border appears slightly wider than right (~55/45 L/R), top border appears moderately wider than bottom (~60/40 T/B) - acceptable for the grade range. The white borders show no obvious toning or staining visible at this resolution. Corners appear reasonably sharp with no obvious rounding visible on the two near corners, though the image angle and small card size make precise corner assessment difficult - the far corners are not clearly resolved. Surface gloss appears present with no obvious creases or major print defects visible, consistent with the seller's NM-MT claim, but the photo resolution and angle prevent confirmation of subtle corner wear or surface issues that would separate a 6 from a 7. Rough cut edges appear normal for the 1966 Topps Batman series and are not penalized.
