Estimated Market Value
Raw: $5 - $15; Graded (CGC 9.8): $150 - $200. In current 6.0 condition: $8 - $12.
Recent Sales
Recent eBay sales for raw copies in mid-to-high grade average around $10 - $25. Graded 9.8 copies have sold in the $180 range.
Grading Recommendation
Not worth professional grading in current condition. The black mark through the UPC and spine wear likely limit the grade to a 6.0-7.0. The cost of grading exceeds the market value of the book at this tier.
Notable Features
Features appearances by Odin, Zeus, and the Eternals. This is a Newsstand edition with a remainder mark (diagonal line) through the UPC barcode. Essential reading for fans of the Eternals and Marvel mythology.
Authentication Notes
The comic appears authentic based on the age-appropriate paper oxidation (slight tanning visible on edges), the specific 40-cent price point for 1980, and the standard newsstand UPC formatting of the era.
