Avengers #171 arrived in May 1978 as a middle chapter in the celebrated Korvac Saga, the extended storyline that ran through the David Michelinie/George Pérez run and is remembered as one of the strongest team-book arcs of the Bronze Age. The issue advances the mystery surrounding Michael Korvac's growing power and the Avengers' gathering suspicion, with Pérez's increasingly assured linework anchoring the era's visual identity. It is not a first appearance or origin issue, and its value rests on being a well-regarded installment of an admired saga rather than on any single landmark moment.

Market data shows a typical Bronze Age demand curve: certified population is substantial (273 Universal copies across 292 total graded), sales activity is heaviest at the high end, and pricing stays flat and modest through the mid and low grades before rising sharply at 9.4 and above. The 9.8 tier alone accounts for the majority of recorded sales, with year-over-year averages holding steady, indicating consistent collector interest in top-condition copies rather than speculative spikes. Lower and mid-grade copies trade as inexpensive, easily sourced reading copies with little differentiation in price across several grade points.

This is a book collected primarily by Avengers and Korvac Saga completists building out the full storyline run, plus registry-focused buyers chasing high-census 9.8 slots. Raw copies in low and mid grade are widely available and priced accordingly, making them accessible entry points, while the jump to a Universal 9.8 represents the real value inflection point in this title's market, driven by condition scarcity rather than narrative significance.
