Shaded band is the middle half of live Buy It Now asking prices, daily 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

Superman Gum Inc. card #18 1940 R145 PRISON BREAK
Estimated grade: 3 (2–4) · LOW confidence · asking $349.00

Centering estimate: left/right borders appear roughly 60/40 favoring left, top/bottom roughly 55/45 - acceptable for the era. However, the most critical issue is a highly visible horizontal crease running across the mid-section of the card, clearly evident in the photo where the two halves are visibly misaligned/offset - this alone caps the grade at VG (3) or lower. Corners show rounding consistent with heavy handling, with the lower-left corner appearing particularly soft. Surface displays significant toning and paper aging typical of this 1940 gum card stock, with color oxidation throughout. The crease is the dominant defect here; without corner closeups the range is widened, but the crease and corner wear strongly suggest a PSA 2-3 range.
