Comic Description

A landmark key issue in Marvel history. In this story, Steve Rogers (operating as 'The Captain' in the black/red/white suit) lifts Mjolnir, Thor's hammer, to hand it back to Thor during a battle against Grog and the Seth's demons. This proves Steve Rogers' worthiness, a major character beat referenced later in the MCU.

Condition & Value

Condition Grade

Fine/Very Fine (CGC 7.0)

Condition Details

Moderate spine stress and color-breaking ticks along the left edge. Visible creasing at the bottom left corner across the barcode. Edge wear and slight blunting on the top and bottom right corners. Minor surface scuffing and tanning on the white cover borders.

Estimated Market Value

Raw: $30 - $45; Graded (9.8): $250 - $350; Graded (7.0 as shown): $50 - $65.

Recent Sales

Recent raw newsstand copies in mid-to-high grade sold between $35 and $55 on eBay (late 2023/2024). High-grade 9.8 CGC copies consistently fetch over $300 due to key significance.

Grading Recommendation

Currently not worth professional grading unless it could achieve a 9.6 or higher. The visible corner crease near the barcode and spine ticks likely cap this at a 7.0–7.5. A press and clean might help, but the cost of grading would outweigh the current market value for this specific condition.

Notable Features

First time Steve Rogers (Captain America) lifts Thor's hammer Mjolnir. Newsstand Edition with UPC. Part of the 'The Captain' era of Steve Rogers' history.

Authentication Notes

Authentic 1980s newsstand print. Features correct 75-cent price point for 1988 and appropriate paper oxidation/tanning for the era. Spine ticks and ink density are consistent with copper-age printing methods.
