Collecting the Joker: a beginner's practical guide

The Joker was born in the pages of Batman #1, published in Spring 1940. He was created by Bill Finger, Bob Kane, and Jerry Robinson, and shares that historic issue with the first appearance of Catwoman. Batman's greatest enemy, he has remained DC's most reprinted, adapted, and collected character after the Dark Knight himself. The 2019 film Joker starring Joaquin Phoenix grossed over $1 billion worldwide — the first R-rated film ever to cross that mark — and renewed collector demand for his key issues.

This guide is for beginners: it separates the affordable issues you can buy tomorrow from the six-figure grails that require a museum-level budget, and flags the Batman #1 reprint trap — the most common mistake new collectors make. Every figure in this guide comes from our eBay estimator (eBay.fr + eBay.com, June 2026) or from documented auction records.

The Batman #1 trap: don't fall for it

Our eBay estimator returns a median of €7 for Batman #1 across 100 listings. Warning: that figure is overwhelmingly driven by modern reprints and facsimile editions — not the 1940 original. Facsimiles and anniversary reprints are abundant on eBay, and they look the part. The real Batman #1 from 1940 is a museum-tier trophy: a CGC 9.4 copy (the only copy ever certified at that grade) sold for $2,220,000 at Heritage Auctions in January 2021. Even a low-grade copy (CGC 0.5) trades in the thousands of dollars. Never treat the €7 eBay median as the value of the 1940 original — it is not. If you see a "Batman #1" listed for €10 on eBay, it is a reprint.

The accessible key: Batman #251 (1973)

For a beginner collector, Batman #251 is the ideal entry point into Joker key issues. In September 1973, writer Denny O'Neil and artist Neal Adams delivered "The Joker's Five-Way Revenge" — restoring the Joker's lethal edge after years of campy portrayals stemming from the 1960s television series. Neal Adams's cover — the Joker standing full-figure, his grin razor-sharp — is one of the most iconic images of the Bronze Age. Our estimator returns a median of €9 across 65 listings: reliable and affordable. In high grade, the documented record is $38,000 for a CGC 9.8 (ComicLink, June 2024) — which illustrates the enormous gap between a reading copy and a near-perfect slab.

The mid-range keys: A Death in the Family (Batman #426–429, 1988)

The "A Death in the Family" arc (Batman #426 to #429, 1988) is the story in which the Joker murders Jason Todd, the second Robin — with readers voting his fate by telephone, the result decided by a margin of just 72 votes. Script by Jim Starlin, art by Jim Aparo. These issues remain the most sought-after "modern" Joker keys outside the Golden Age. Among them, only Batman #429 has enough listings for a reliable median: €28 across 32 listings. Issues #426 (11 listings) and #428 (12 listings) are too thinly listed to cite a reliable figure — check recent sold prices directly. Batman #427 (16 listings, median €21) sits at the edge of reliability.

The Golden Age grail: Detective Comics #168 (1951)

Detective Comics #168 (February 1951) reveals the Joker's origin: he was once the Red Hood, a failed criminal who fell into a vat of chemicals that bleached his skin, turned his hair green, and locked his face into a permanent grin. Our estimator returns only 4 listings for this issue — too thin to cite a reliable median. Auction records are the only valid reference: a CGC 9.4 copy sold for $324,000 (November 2022); a CGC 6.0 copy realised $23,345 (2022). A low-grade copy is theoretically within reach of a serious collector, but this is firmly specialist territory.

The cult classic: Batman: The Killing Joke (1988)

Batman: The Killing Joke (1988, script by Alan Moore, art by Brian Bolland) is the story that has most deeply shaped the Joker's mythology in popular culture. Our estimator does not cover this title. On the open market, the original print run was large and first printings remain relatively affordable: expect to pay $50–$75 for an ungraded copy in solid condition, or $150–$250 for a CGC 9.8 based on recent data. This is not a scarcity grail — it is a reading classic, and a natural first purchase for any thematic Joker collection.

How to build your collection: practical advice

Start with Batman #251: it is the most accessible Joker key, with a median around €9 and 65 active listings. For modern arcs — the Killing Joke, Death in the Family — first printings are findable below €50 in reading condition. Be cautious with issues that have fewer than 15 eBay listings: the median is not representative. On grading, a "Very Fine" (VF 8.0) copy strikes a good balance between presentation and price — CGC slabbing is best reserved for major keys where it justifies the cost. And above all: whenever you see a Batman #1 at a low price, always confirm whether it is a facsimile before buying.
