Condition & Value
Condition Grade
Very Good (CGC 4.0)
Condition Details
Visible spine stress and color-breaking ticks; significant blunting and minor paper loss on the bottom left corner near the spine; edge wear along the right side; minor vertical creasing on the right half of the cover; slight yellowing/tanning of the white paper areas due to age.
Estimated Market Value
Raw: $35 - $60; Graded (CGC 4.0): $100 - $130
Recent Sales
Recent 4.0 equivalents have sold for approximately $45-$55 raw on eBay. A CGC 7.0 sold for roughly $250 recently, while lower grades (3.0) stay around the $30 range.
Grading Recommendation
Not recommended for professional grading unless for personal preservation. The current condition would likely land between 3.5 and 4.5. The cost of grading (fees + shipping) would nearly equal the market value of the book in this condition.
Notable Features
First appearance of Bizarro-Batman. Key Silver Age issue featuring the Joker and Bizarro Superman. Noted for its 'checkered' top banner branding from DC in the mid-60s.
Authentication Notes
The 12-cent cover price, aging of the paper stock (slight oxidation), and the 1966 DC logo/Comics Code Authority stamp are all consistent with an original Silver Age copy.
