Grading Recommendation
Optional. While a 7.0 is a decent grade, the current market value of this specific silver-age issue may not justify the grading costs unless you intend to preserve it for a long-term collection. A professional clean and press might push it closer to a 7.5 or 8.0, which would increase the ROI.
Notable Features
First appearance of the Unimaginable. Metamorpho declines JLA membership. Classic Mike Sekowsky cover art. Silver Age DC 12-cent price variant.
Authentication Notes
The comic exhibits authentic 1960s newsprint characteristics. Cover gloss is consistent with DC's mid-60s production. Staples and paper aging are consistent with the 1966 publication date.
