Condition & Value

Condition Grade

Fine (CGC 6.0)

Condition Details

Visible spine stress, slight color break on the spine, corner blunting (especially top and bottom left), minor edge wear on the right side, and a slight vertical curve due to storage. The UPC barcode has a black mark through it, which is typical for certain UK distribution or remaindered copies.

Estimated Market Value

Raw: $5 - $15 USD / Graded: $35 - $60 USD. Note: UK Price variants generally have a niche market compared to US cents editions.

Recent Sales

Recent sales for mid-grade raw copies range from $5 to $12. Higher grade (9.0+) US copies fetch around $25-$40.

Grading Recommendation

Not recommended for professional grading. The costs of grading (CGC/CBCS) usually exceed the market value of the book in this condition unless it holds significant sentimental value. A clean and press might improve the grade, but likely not into the 'investment' tier.

Notable Features

Early interior art by Frank Miller. 12p British Pence Price Variant. Features a 'strikethrough' mark on the UPC, which is often found on comics shipped overseas or sold through specific retail channels.

Authentication Notes

Authentic 1970s newsprint production. Colors and paper aging are consistent with late Bronze Age Marvel books. Staple placement and cover gloss appear consistent with standard Marvel production from this era.
