STRANGE ADVENTURES #221

Cover shows moderate wear consistent with a mid-grade Silver Age book: slight rounding and minor fraying at the top corners, a faint vertical crease near the left edge, and light surface scuffing across the blue background. Spine appears mostly flat with a couple of light stress lines but no major color break visible. Book is housed in a protective sleeve, and interior pages and back cover were not assessed, so grade is based solely on the visible front cover.

Strange Adventures #221 arrived in December 1969, near the close of DC's long-running science-fiction anthology title that had launched in 1950. By this point the series had moved past its celebrated Deadman feature (which had ended a few issues earlier) and returned to standalone speculative-fiction and fantasy shorts in the anthology format that defined the title for most of its run. The book reflects the tail end of the Silver Age science-fiction anthology boom, a period when DC's mystery and sci-fi lines were winding down in favor of the superhero-dominant market that would define the 1970s.

Market activity for this issue is thin, consistent with a late-run anthology number without a first appearance, notable death, or classic cover attached to it. The certified population is small, with only 25 total graded copies and a single CGC 9.8 on record, and sales data across the grade spectrum are sparse but internally consistent, showing a typical steep curve where value stays flat through mid-grade before climbing sharply at the top of the census. There is no meaningful key-issue premium driving demand; value here tracks general collector interest in the Strange Adventures series and in high-grade Silver Age anthology material generally.

This is a book that appeals mainly to completists building a run of Strange Adventures or DC's late-1960s mystery line, rather than to speculative or character-driven buyers. Lower and mid-grade raw copies trade cheaply and are readily available, while the very small high-grade population means a clean 9.8 commands a real premium relative to the rest of the curve, appealing to census-chasing grade collectors rather than mainstream key-issue investors.
