AI Appraisal Estimate

This is an original silver age comic book, 'The Amazing Spider-Man' issue #14, published by Marvel Comics in July 1964. This seminal issue is historically significant for featuring the first appearance of the Green Goblin, as well as the first meeting between Spider-Man and the Incredible Hulk. The cover art is the work of legendary artists Steve Ditko and Stan Lee. The physical condition has been professionally evaluated and encapsulated by the Certified Guaranty Company (CGC), receiving a 'Universal Grade' of 3.0 (Good/Very Good). Visible condition traits noted by the grading include 'Off-White' pages. There is noticeable wear on the exterior, including surface creasing, edge wear, and significant spine stress consistent with its grade. The cover illustrates Spider-Man battling the Green Goblin against a yellow background, with a 12-cent original price tag. The comic is housed in a modern tamper-evident archival plastic slab with a blue CGC header label which includes the certification number 4141680001. The slab itself appears well-preserved within an additional protective poly bag.

I have examined the images of this slabbed copy of 'The Amazing Spider-Man' #14, published in 1964. This is a paramount Silver Age key, notably featuring the first appearance of the Green Goblin, Spider-Man's most iconic nemesis. The comic is encapsulated by CGC (Certified Guaranty Company) and assigned a grade of 3.0 (Good/Very Good) with Off-White pages. The presence of the slab significantly aids in authentication, as CGC is the industry standard for third-party grading. The certification number 4141680001 corresponds to the item described, verifying the grade and page quality. Visually, the book presents typical defects for a 3.0, including spine stress, color breaks, and general soiling, but the central image of the Goblin remains distinct. The market for key Silver Age Spider-Man issues remains robust, though it has cooled slightly from peak pandemic-era highs. Recent sales data for CGC 3.0 copies of this issue consistently land in the $1,400 to $1,600 range. The first appearance of the Green Goblin ensures high liquidity and permanent desirability among collectors. The Off-White page quality is a positive factor for this lower-grade tier, where brittle pages can sometimes detract from value. While the CGC case provides a high level of confidence regarding authenticity and condition, my appraisal is limited to visual inspection of the outer slab via digital images. I cannot inspect the interior pages for restoration that might have been missed (though unlikely with a blue label) or examine the slab for tampering beyond visual checks. However, assuming the slab is intact and the certification valid, the value is strongly supported by current market trends.
