Every Friday we track the biggest gainers and losers among key issues based on what buyers actually paid on eBay — completed sales only, no asking prices, no guesswork. This week’s board is a study in contrasts: Kirby-era debuts added heat on the upside while a slate of DC Copper- and Bronze-Age keys gave back ground. As always, every book below is a key, and every move is backed by multiple recorded sales.
Top Gainers
| Title | Issue | Publisher | Current | Prev | Change |
|---|---|---|---|---|---|
| Mister Miracle (1971) | No. 1 | DC Comics | $170 | $60 | +$110 / +183.33% |
| Magnus: Robot Fighter (1991) | No. 1 | Valiant Entertainment | $20 | $10 | +$10 / +100% |
| The Eternals (1976) | No. 1 | Marvel | $30 | $20 | +$10 / +50% |
| The Amazing Spider-Man (1963) | No. 406 | Marvel | $10 | $5 | +$5 / +100% |
Mister Miracle (1971) No. 1 — DC Comics
Writer: Jack Kirby | Penciller: Jack Kirby
Scott Free’s debut tacked on +$110 (+183.33%) to $170 on 7 recorded sales. The median sold at $190, a notable premium over the current comp, suggesting buyers chased higher copies through the week. As the first appearance of Mister Miracle (Scott Free), Thaddeus Brown, and Oberon, the move looks like steady collector demand for Kirby’s Fourth World rather than a one-off spike.
Magnus: Robot Fighter (1991) No. 1 — Valiant Entertainment
Writer: Jim Shooter | Penciller: Art Nichols
Up +$10 (+100%) to $20 across 3 recorded sales. The median at $16 trails the current comp, which hints the top sale may have pulled the average up. With key-status in the Valiant lane (noted for W-23), this reads as a light-volume pop that speculators occasionally revisit.
The Eternals (1976) No. 1 — Marvel
Writer: Jack Kirby | Penciller: Jack Kirby
Kirby again: +$10 (+50%) to $30 on 6 recorded sales. The median at $30.43 essentially corroborates the new level, pointing to a firming floor for the first appearances of the Eternals, Ikaris, Kro, Brother Tode, and Margo Damian among the Deviants.
The Amazing Spider-Man (1963) No. 406 — Marvel
Writer: J M DeMatteis | Penciller: Angel Medina
Carolyn Trainer’s first as Lady Octopus doubled to $10 (+$5, +100%) on 3 recorded sales, with a $9.99 median lining up with the comp. Lacking a clear news catalyst, the bump appears to be driven by speculator activity in the 90s Spidey pocket.
Top Losers
| Title | Issue | Publisher | Current | Prev | Change |
|---|---|---|---|---|---|
| The Avengers (1963) | Annual No. 10 | Marvel | $60 | $140 | -$80 / -57.14% |
| Marvel Spotlight (1971) | No. 32 | Marvel | $30 | $80 | -$50 / -62.5% |
| Tales of Suspense (1959) | No. 93 | Marvel | $30 | $80 | -$50 / -62.5% |
| Detective Comics (1937) | No. 583 | DC Comics | $25 | $50 | -$25 / -50% |
| Detective Comics (1937) | No. 585 | DC Comics | $5 | $25 | -$20 / -80% |
| Static (1993) | No. 1 | DC Comics | $30 | $45 | -$15 / -33.33% |
| Batman (1940) | No. 405 | DC Comics | $10 | $20 | -$10 / -50% |
The Avengers (1963) Annual No. 10 — Marvel
Writer: Chris Claremont | Penciller: Michael Golden
Down -$80 (-57.14%) to $60 on 5 recorded sales, with a $64 median that sits just above the comp. As the first appearance of Rogue (and a cameo for Madelyne Pryor as a child), this week’s slide looks like cooling speculator demand rather than a structural shift.
Marvel Spotlight (1971) No. 32 — Marvel
Writer: Archie Goodwin | Penciller: Sal Buscema
Jessica Drew’s debut slipped to $30 (–$50, –62.5%) on 5 recorded sales. The $30 median matches the comp, suggesting the market reset its floor this week.
Tales of Suspense (1959) No. 93 — Marvel
Writer: Stan Lee | Penciller: Jack Kirby
M.O.D.O.K.’s cameo issue closed at $30 (–$50, –62.5%) across 5 recorded sales. A $31.49 median nearly mirrors the comp, implying stabilization around this lower level after the drop.
Detective Comics (1937) No. 583 — DC Comics
Writer: Alan Grant | Penciller: Norm Keith Breyfogle
First Ventriloquist and Scarface eased to $25 (–$25, –50%) on 5 recorded sales. The $19.17 median undercuts the comp, which leaves room for further downside if supply stays heavy.
Detective Comics (1937) No. 585 — DC Comics
Writer: Alan Grant | Penciller: Norm Keith Breyfogle
Ratcatcher’s first appearance fell to $5 (–$20, –80%) on 5 recorded sales, with a $5.67 median essentially confirming the new floor. That’s a full round-trip back to bargain-bin pricing.
Static (1993) No. 1 — DC Comics
Writer: Dwayne McDuffie | Penciller: John Paul Leon
Virgil Hawkins cooled to $30 (–$15, –33.33%) on 4 recorded sales. The $28.63 median is close enough to the comp to suggest a soft slide rather than a capitulation.
Batman (1940) No. 405 — DC Comics
Writer: Frank Miller | Penciller: David Mazzucchelli
Year One’s second chapter halved to $10 (–$10, –50%) on 5 recorded sales. A $9.79 median tracks the comp, pointing to broad but orderly retracement.
On Our Radar
Mister Miracle (1971) No. 1 — DC Comics
Writer: Jack Kirby | Penciller: Jack Kirby
With a +$110 (+183.33%) move to $170 on 7 recorded sales and a higher $190 median, this one shows both momentum and depth of bids. If more copies hit the market next week, watch whether the median keeps leading the comp — that’s usually the tell for a sustained repricing rather than a single sale pulling the average.
What This Means For Collectors
Kirby-era keys found buyers at higher levels this week while several DC and Marvel staples reset to lower, arguably healthier floors. Use the medians as your compass: where they sit above the current comp (Mister Miracle No. 1), the trend may have room; where they trail (Detective Comics No. 583), patience and tight bids are your edge.
