Stand at any comic show table long enough and you'll hear it. One collector wants a CGC 9.8 of a modern first appearance. The next one says modern books are "printed by the truckload" and the only real keys are 50+ years old. Both of them can point to 2026 and say, "See?"
At the very top, Golden Age books keep rewriting the record book. In January 2026, a CGC 9.0 copy of Action Comics #1 sold privately for $15 million, according to CGC and Guinness World Records. That came just two months after a CGC 9.0 Superman #1 sold for $9.12 million at Heritage Auctions. Meanwhile, the momentum chart belongs to modern books. GoCollect's September 25 review of its Collectible Price Index put the Modern Age index at 4,863, up roughly 18–20% over the past year and the strongest of the five eras it tracks. Its Silver Age index, by comparison, sat at 1,621 after a slow climb back from a winter dip.
So which side is right? Let's argue both as fairly as we can, then tell you where we land at Choice Custom Collections.
Collectibles, not investments. Figures are historical and dated. Past performance does not guarantee future results. Not investment advice.
The case for modern keys
1. That's where the momentum is
By GoCollect's numbers, the Modern Age index rose almost without interruption over the past year, led by high-grade sales of Invincible #1, The Walking Dead #1 and Ultimate Fallout #4 (the first Miles Morales). Collectors who grew up with those characters are now the buyers, and they're paying for them.
2. You can actually own the best copy
With a modern book, a 9.8 is a realistic target. You can buy the grade at the top of the scale instead of settling for a 3.0 with a torn cover. And for most modern books, restoration is a much smaller worry than it is with an 80-year-old comic.
3. The characters are still growing
A modern first appearance can still gain a TV series, a game, or a new run. CGC's own October 2026 Hot List included Green Lantern #25 (2008), the first appearances of Atrocitus and Larfleeze, because HBO's Lanterns has fans watching for Green Lantern lore. That kind of story is still being written for modern characters.
4. The entry price is human
Most collectors will never own a Golden Age grail. A strong modern key lets you collect the books you love on a normal budget, and that's what keeps the hobby alive.
The case for Golden and Silver Age
1. Scarcity is built in
Old comics were read, rolled up, traded, and thrown away. CGC says Superman #1 sold out a print run of half a million copies in 1939, yet only 209 copies are recorded in CGC's census today, and fewer than half of those carry the blue Universal label. No modern book will ever have that kind of attrition, because collectors bagged and boarded them on day one.
2. The value doesn't depend on a streaming show
Action Comics #1 doesn't need a casting rumor. The great Silver Age keys, from Amazing Fantasy #15 to Fantastic Four #1, are the foundation of the medium. Their demand comes from history, not from this year's release schedule.
3. Modern hype can disappear
Plenty of collectors learned this the hard way after 2021–2022. One 2026 market analysis from My Comics Collection describes modern 1:10 ratio variants as having lost almost all of their premium and many secondary screen-driven first appearances as well off their peaks. A book bought because of a rumor can lose its premium when the rumor fades.
4. Mid-grade is still collectible
You don't need a 9.8 to own a meaningful Silver Age book. GoCollect builds its Silver Age index from sales in CGC grades 2.5–8.5, because that's where most of these books actually trade. A solid, unrestored mid-grade key has a real market.
The fine print both sides skip
The indexes aren't measuring the same thing. GoCollect's Modern index uses CGC 9.0–9.8 sales, its Silver index uses 2.5–8.5, and its Golden index uses 0.5–8.0. Comparing them head to head is closer to comparing a sprint to a marathon.
"Key" means something specific. A first appearance, an origin, a famous death, or an iconic cover. A variant cover of an ordinary issue isn't a key, no matter how small the ratio.
Label color matters. On a CGC slab, blue is Universal (unrestored) and purple means restored. A restored Golden Age book can be a great way to own history, but it should be priced and described as restored.
There's a middle ground. The 1980s–early '90s Copper Age (Amazing Spider-Man #300, New Mutants #98, Batman Adventures #12) sits between the two camps. GoCollect's Copper Age index climbed roughly 6–7% from its early trough.
If you're deciding whether a book is worth slabbing at all, our Raw vs. Graded in 2026 breakdown walks through that math.
A 4-question test before you buy any key
- Would this book matter if no movie or show existed? If the answer is no, you're buying a headline, not a key.
- How many high-grade copies are out there? Check the grader's census. A thousand 9.8s is a different market than twelve.
- What have recent sold copies done, in the same grade and the same label color? Not asking prices, and not a 9.8 comp for your 9.4.
- Can you afford the grade you actually want? A clean 6.0 Silver Age key you love beats a 9.8 modern book you only bought to flip.
Where we land
We're not Team Modern or Team Vintage. We're Team Story. The books that hold up are the ones that matter to comics history, whatever year they were printed.
- Modern keys: yes, when it's a true first appearance of a character with staying power, in a high grade, bought on sold comps. Skip ratio variants of ordinary issues and pure rumor plays.
- Golden and Silver Age: yes, in the best-looking unrestored copy your budget allows. A mid-grade blue label beats a high-grade book with surprises.
- Copper Age is where many collectors find the balance of nostalgia, availability and price.
Full disclosure: much of what we carry today is high-grade Marvel keys from the 1980s and '90s, so we have a stake in the middle of this argument. We still think the right answer is the book that fits your story.
