Comic Description

Nemesis was ACG's attempt at a superhero during the height of the Silver Age, possessing powers and a costume that slightly deviated from their usual supernatural fare.
Condition & Value
Condition Grade
Good/Very Good (CGC 3.0)
Condition Details
Visible surface wear and scuffing on the top center of the cover. Significant spine stress and color-breaking ticks. Corner rounding and blunting. Yellow circular sticker on the right side. Moderate edge wear and general soiling. Appears to be stored in a wrinkled polybag which obscures some surface details but reflects significant general handling wear.
Estimated Market Value
Raw: $10.00 - $20.00 USD; Graded (CGC 3.0): $40.00 - $60.00 USD
Recent Sales
High-grade copies (VF or better) can fetch $100+, but low-grade copies consistently sell in the $10-$20 range on secondary markets like eBay.
Grading Recommendation
Not recommended for professional grading. The cost of the grading service likely exceeds the market value of the book in this condition. It is a great 'reader copy' or filler for a run, but not a high-value investment piece.
Notable Features
Nemesis appearance. Silver Age ACG title. 12c price point. Kurt Schaffenberger cover art (famed Superman/Lois Lane artist).
Authentication Notes
The wear patterns, paper aging, and distinctive ACG 12-cent trade dress are consistent with original 1966 printings. No known high-quality reprints exist for this specific issue that would cause confusion.
