Condition & Value

Condition Grade

Condition Details

Visible color-breaking spine stress ticks; corner blunting particularly on the bottom right; slight edge wear along the top; minor surface scuffing on the dark purple background; vertical alignment looks slightly off (cut-related).

Estimated Market Value

Raw: $5 - $15 USD / Graded: $40 - $60 USD

Recent Sales

Recent raw copies of mid-to-high grade sold between $8 and $12. Graded 9.0+ copies rarely exceed $70 as this is not a key issue.

Grading Recommendation

Not recommended for professional grading. The costs of grading and shipping would likely exceed the market value of the book in this condition. It is best kept as a reader or filler copy.

Notable Features

Features the 20p UK Price Variant (intended for the United Kingdom market). Significant for the Spider-Man head in the UPC corner box, which was standard for direct market/non-newsstand books of this era.

Authentication Notes

Authentic bronze age paper stock; correct color saturation for the era; the '20p' price stamp is consistent with genuine UK variants of 1981.
