Each month we run the same simple screen: non-key back issues whose last four consecutive eBay sold-price reads have each ticked upward, with the most recent read representing the current market price. It’s a short-window momentum check, not a long-term verdict, but it reliably surfaces books the broader market may be waking up to. As always, early streaks can fade as quickly as they form — treat this as a signal to look closer, not a guarantee of where the next sale will land.
House of Secrets (1956) No. 106 — DC Comics
Writer: | Penciller: Bernie Wrightson
$40 → $75 → $95 → $210 across four reads, +425% (from May 7, 2026 to September 25, 2026)
Wrightson’s name alone pulls a deep-collector audience, and Bronze Age DC horror has been steadily rediscovered by readers who value atmosphere over capes. This issue’s climb from $40 to $210 across four consecutive reads suggests fresh demand finding limited supply in presentable copies.
Why it might still be early: Even after the spike, this sits in a range where strong eye appeal can still surprise on auction night. Wrightson pages and covers attract cross-genre buyers, and that overlap can buoy prices beyond typical run-book behavior.
Watch for: Crisp registration and unbroken color along the spine — these anthologies often show handling wear. Be ready for volatility; a short burst like this can retrace if the next listing undercuts.
The Amazing Spider-Man (1963) No. 206 — Marvel
Writer: Roger Stern | Penciller: John Byrne
$5 → $10 → $20 → $40 across four reads, +700% (from June 10, 2026 to October 2, 2026)
Late Bronze ASM by Roger Stern with John Byrne is catnip for run-builders who want quality storytelling without Silver Age price tags. The move from $5 to $40 looks dramatic in percent terms, but it also signals a pocket of demand for sharp mid-run issues with creator pedigree.
Why it might still be early: Once collectors zero in on a creative team stretch, adjacent issues tend to follow as people fill gaps. If copies at the new level are still relatively affordable to the broader ASM audience, momentum can persist while supply adjusts.
Watch for: Clean whites in the logo box and minimal spine ticks — newsstand-era handling often dings these. If the next sale comes in soft, don’t mistake a single data point for a trend break; one undercopy can reset comps temporarily.
The Avengers (1963) No. 49 — Marvel
Writer: Roy Thomas | Penciller: John Buscema
$30 → $35 → $65 → $110 across four reads, +266.7% (from April 17, 2026 to August 28, 2026)
Silver-to-Bronze cusp Avengers with Roy Thomas and John Buscema blends historical significance with classic team-era art. A rise to $110 on the fourth read suggests collectors are leaning into Buscema’s run beyond the obvious tentpoles and cherry-picking strong covers and stories.
Why it might still be early: When a specific run catches, strong mid-tier issues can re-rate as buyers aim for presentable copies before prices drift. Continued interest in late Silver Age Marvel generally keeps a floor under well-loved team books.
Watch for: Off-white to white pages and centering — older Avengers can present wonderfully when registration is tight. If you’re grading-bound, pre-screen for corner blunting; minor improvements in apparent condition can mean outsized gains in this range.
The Silver Surfer (1968) No. 14 — Marvel
Writer: Stan Lee | Penciller: John Buscema
$160 → $165 → $205 → $250 across four reads, +56.3% (from May 22, 2026 to September 25, 2026)
Even with a smaller percentage move than our other picks, a four-read step-up at higher dollar amounts is noteworthy. Lee and Buscema on this series draw sustained, cross-era demand, and the bump to a $250 current read underscores that buyers are bidding confidently for cleaner copies.
Why it might still be early: Silver Surfer’s core audience is resilient; when nice examples appear, they tend to sell. If supply remains thin in higher-presenting raw or graded copies, incremental pushes can hold as new comps anchor the range.
Watch for: Smooth, reflective cover areas are unforgiving — tilt-test for surface scuffs before you price aggressively. Expect wider bid-ask spreads here; patience can matter more than chasing the very next auction.
Lobo (1990) No. 1 — DC Comics
Writer: Keith Giffen | Penciller: Simon Bisley
$15 → $20 → $35 → $45 across four reads, +200% (from August 28, 2026 to September 25, 2026)
The early-’90s Giffen/Bisley blend of attitude and painted punch has an evergreen cult following. This quick pop to a $45 current read hints that collectors are re-engaging with foundational issues of the character rather than just chasing nostalgia soundbites.
Why it might still be early: As sets reform around creator-driven runs, adjacent mini-series and follow-ups often see sympathetic bumps. If the baseline for solid raw copies is resetting, there may be room for selective upgrades without stretching.
Watch for: Color rub and spine stress along the darker inks — they’re common and can separate a mid-grade from a strong-looking VF. Listings with clear, natural light photos tend to outperform; factor that into what you consider a true comp.
How To Use This List
These picks are here because each book’s last four eBay sold-price reads climbed in sequence, with the fourth read serving as the current price. That’s a momentum signal across a short window — nothing more, nothing less. Momentum can stall if the next copy is weaker, if a seller undercuts to move inventory, or if a brief wave of attention passes. Treat these as prompts to investigate condition, supply, and your own time horizon.
If you decide to take a shot, remember: not every rising line is a durable trend. Focus on eye appeal, confirm grading notes and return policies, and be comfortable walking away if a listing’s photos don’t justify the ask. The best use of this list is to get ahead of the herd — patiently, with discipline — rather than chase it.
