Estimated Market Value
Raw: $150-$225; Graded (9.0): $450-$600
Recent Sales
Recent sales for mid-grade (6.0) copies range from $40-$60. High-grade copies (9.0+) are scarce and have reached $500+ in recent Heritage/eBay auctions.
Grading Recommendation
Highly recommended for grading. Because this is a Silver Age key (1st Bizarro-Batman) and appears to be in 9.0+ condition, the value multiplier for a certified high grade is significant. A professional press could potentially push this toward a 9.2 or 9.4.
Notable Features
First appearance of Bizarro-Batman. First appearance of Bizarro-Joker (Bizarro-World version). iconic Curt Swan cover with 'checkered' top border typical of 1966 DC issues. Silver Age key issue.
Authentication Notes
Consistent with 1960s DC manufacturing. Correct 12-cent price point. Paper aging is appropriate. The '10c' stamp is a common vintage bookstore/UK distributor marking and does not typically indicate a counterfeit.
