CGC 6.0 copies have recently sold in the $130-$150 range. Mid-grade raw copies typically auction between $50 and $80 depending on the intensity of the cover colors.
Grading Recommendation
Moderate recommendation. While a key Silver Age issue, the value in 6.0 grade may not significantly outweigh grading fees after shipping. A professional press could potentially bump this to a 7.0, making it more viable for encapsulation.

Authentication Notes
Authentic silver age copy. Features correct 12-cent cover price, DC 'checkerboard' top trade dress, and era-appropriate paper oxidation. Staple placement appears original.
