SINGLE HIGEST GRADED. Adventures into the Unknown #135 (ACG, 1962) is a professionally graded comic suited for collectors building focused runs, character collections, or high-grade genre sets. Horror, mystery, and supernatural anthology comics have become increasingly desirable among collectors who appreciate atmospheric covers, genre storytelling, and the scarcity of sharp certified examples. The issue offers strong shelf appeal as a slabbed collectible, particularly for buyers who prefer authenticated copies with clear grade visibility and reduced uncertainty compared with raw examples. The certified 9.4 grade adds marketplace confidence and makes the book easier for collectors to compare, display, and add to registry-style runs. For Shopify buyers, the combination of title recognition, visual presentation, and third-party certification helps position this book as a collectible rather than a casual reader copy. Collectors may be drawn to the issue for its era-specific artwork, storyline placement, and the opportunity to fill a tougher high-grade slot without having to search through raw copies. This listing is written conservatively for experienced comic buyers who understand that demand can vary by page quality, census availability, cover desirability, and recent comparable sales.
