Visible spine stress and 'ticks' along the left edge, slight blunting of the corners (particularly lower right), minor edge wear, and a small circular price stamp/sticker residue ('20') near the title. Moderate shelf wear consistent with age.
Estimated Market Value
Raw: $60 - $90; Graded (CGC 5.0): $120 - $150
Recent Sales
Recent eBay sales for raw copies in mid-grade (4.0-6.0) range from $55 to $110. CGC 7.0 copies have recently sold for approximately $250.
Grading Recommendation
Moderate recommendation. At a mid-grade level, the cost of grading may equal the value added. However, it is a Silver Age key featuring the first appearance of Dr. Polaris. A professional clean and press could potentially bump it to a 5.5 or 6.0.
Notable Features
First appearance and origin of Dr. Polaris. Classic Gil Kane cover art. Iconic Silver Age DC title.
Authentication Notes
The comic appears to be an authentic 1963 original. The ink absorption on the cover and the 12-cent price point are consistent with DC's production in the early 1960s. The '20' price mark appears to be a vintage secondary market markup common in comic shops of the 70s or 80s.
