MYSTERY IN SPACE #64

This 1959 10¢ Silver Age issue shows notable wear consistent with a mid-grade copy: heavy spine stress with visible whitening and small ticks along the spine edge, a vertical crease running through the DC logo area, and soft/rounded corners. There is a small stain or discoloration at the upper right near the price box, and the cover shows overall wear and slight color loss, particularly at the spine. The book appears to be housed in a protective sleeve; interior pages and back cover were not visible for assessment.

Mystery in Space #64 arrives from the heart of DC's late-1950s science-fiction anthology line, published as the Adam Strange feature was cementing its place as one of the company's signature Silver Age creations. Gardner Fox's scripting and Carmine Infantino's clean, forward-looking pencils defined the strip's visual identity, blending pulp-adventure plotting with the era's optimistic space-age imagery. While this issue does not carry a first appearance, origin, or other landmark distinction, it is a representative entry in a tightly followed run that collectors pursue as a complete set built around Strange's Rann-based adventures.

Market activity reflects a modestly traded book rather than a headline key: certified sales cluster in the 7.0 to 9.0 range, with prices climbing from roughly the low hundreds at 7.5-8.0 to the high $200s at 9.0, a fairly typical curve for a mid-tier Silver Age anthology title. Demand is driven primarily by Adam Strange completists and Infantino/Fox admirers rather than speculative first-appearance buyers, which keeps the book's price growth steady but unspectacular. The absence of any certified copy above 9.2 on a census of only 25 to 27 graded books underscores how scarce true high-grade survivors are, even though overall demand remains moderate.

This is a book that trades hands most often as part of a broader Mystery in Space or Adam Strange run rather than as a standalone target. Lower-grade raw copies serve reading and gap-filling collectors at accessible prices, while mid-grade raw copies appeal to those assembling presentable sets without chasing top census standing. A true 9.8 has never been certified, so any future submission at that level would likely command a substantial premium purely on condition rarity, positioning it as a novelty grail for census-chasers rather than a book with an established high-end trading history.
