Shaded band is the middle half of live Buy It Now asking prices, weekly intervals; the line is the median. Auctions are excluded - a climbing bid is not an asking price. The scale follows the asking prices, so a sale well outside them is pinned to the edge rather than flattening the band.middle halfconfirmed salebest offer, at its cap

Bat on a Buoy 1966 Topps Batman Riddler Back #31 Robin
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 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.

TOPPS BATMAN Riddler Back 1966 TV SHOW MOVIE CARD #31 Bat On
Estimated grade: 3 (2–4) · MEDIUM confidence · asking $10.00

Centering estimate: left border appears slightly wider than right (~55/45 L/R), top border moderately wider than bottom (~60/40 T/B) — centering is passable but not tight. The surface shows multiple distracting scuffs and scratches across the image area, consistent with handling wear or storage rub; gloss appears heavily diminished. Corners show visible rounding on at least two corners visible in the photo (top-left and top-right appear blunted), and the card back edges show chipping/wear on the black border. No obvious hard crease is confirmed from this single image, but surface wear and corner rounding alone point toward VG (3) range; if a crease is present on the reverse or the surface wear is deeper than it appears, this could fall to GOOD (2). A raw PSA submission at this condition would likely return a 2-3.

1966 Venezuela Topps Batman Riddler Back #31 Bat on a Buoy
Estimated grade: 2 (1–3) · MEDIUM confidence · asking $19.99

Centering estimate: left/right borders appear roughly 50/50, top/bottom roughly 55/45 — centering itself is not the primary issue here. The card surface shows extensive cracking and crazing across virtually the entire face, consistent with paper stock breakdown common in Venezuelan prints stored in humid conditions; this constitutes severe surface damage well beyond simple gloss loss. Multiple deep creases or stress lines are visible running diagonally across the image area. Corners cannot be assessed with precision due to the overall surface degradation, but the card appears intact without tears or paper loss. The card likely grades PSA 2 (GOOD) due to multiple visible creases and significant surface cracking/soiling, though PSA 1 is possible if the creases are as deep as they appear; a PSA 3 ceiling is generous given the extent of surface damage. Venezuelan Batman cards carry a collector premium as scarcer regional variants, but condition damage will suppress grade regardless.
