Condition & Value
Condition Grade
Fine (CGC 6.0)
Condition Details
Visible spine stress and color-breaking ticks along the left edge. The top right corner shows blunting and light creasing. Minor edge wear on the right side. The blank UPC box shows slight tanning or surface scuffing. Overall image is vibrant but structural wear limits the grade.
Estimated Market Value
Raw: $5 - $15 | Graded (9.0+): $45 - $75
Recent Sales
Recent raw sales for mid-grade copies fluctuate between $3 and $12 USD. High-grade slabbed copies (9.8) can reach over $150, but mid-range slabs (8.0-9.0) often sell for less than the cost of grading fees.
Grading Recommendation
Not recommended for professional grading. The estimated grade of 6.0-7.0 does not justify the grading costs, as the market value for this specific issue in this condition is relatively low.
Notable Features
Early Walt Simonson cover art (years before his legendary run as writer/artist on the title). Notable for the blank UPC box, indicating it was intended for comic shop distribution rather than newsstands.
Authentication Notes
Appears to be an authentic 1978 bronze-age original. The ink saturation on the Thor logo and the era-appropriate paper stock visible at the corners are consistent with Marvel's production standards of that period.
