AVENGERS #56

Cover shows good gloss with mild wear at the corners and light rubbing along the spine, with a couple of faint stress lines visible near the top edge. There is minor edge wear along the left border and the book appears slightly cocked in its protective sleeve; no major creases, tears, or color breaks are evident in this photo. The book is in a protective sleeve which obscures fine surface detail, and the back cover and interior pages were not assessed.

Avengers #56 (September 1968) is best remembered for two things: the death of the original Baron Zemo, the villain whose vendetta against Captain America had driven much of the series' early Masters of Evil storylines, and an extended flashback sequence recounting Captain America and Bucky Barnes' World War II service in unusual depth for the era. Written by Roy Thomas with art by John Buscema, the issue functions as both a payoff to a long-running villain arc and a foundational piece of Cap/Bucky lore that later creators would draw upon, particularly once Bucky's fate became a recurring point of reinterpretation in Marvel continuity. The Avengers lineup of the period — Captain America, Hawkeye, Goliath, Wasp, and Black Panther — anchors the present-day half of the story.

Market data shows a book with broad collector participation across the grade spectrum: over 500 CGC Universal copies on census and steady sales activity from low grade through 9.4, followed by a sharp value escalation at the top end. The gap between 9.6 and 9.8 FMV is pronounced, consistent with a Silver Age team book where high-grade survivors are scarce relative to demand from Avengers and Captain America completists. Recent 90-day and 30-day averages at 9.2 and 9.4 running below the 1-year averages suggest some softening in the mid-high grade tiers, though the 9.8 tier's 1-year average remains well above $1,900, indicating sustained interest at the census summit.

This is a second-tier key that trades most actively among Avengers and Captain America run-builders rather than pure speculators, since neither the Zemo death nor the Bucky flashback carries the crossover cachet of a first-appearance issue. Raw copies in low and mid grade move steadily as affordable pieces of a broader Silver Age Avengers collection, while CGC 9.8 examples command outsized premiums reflecting genuine census scarcity. Expect the book to hold a stable niche demand profile, with upside tied more to renewed attention on Zemo or Bucky in adaptations than to any independent grail status.
