Joker: a complete guide to collecting his key comics

Introduced in 1940, the Joker is Batman's arch-nemesis and one of the most recognisable figures in global popular culture. His publishing history spans three distinct eras: the Golden Age (1940–1951), where he appears from the outset as a killer; the Bronze Age (1973), when Denny O'Neil and Neal Adams restore his menace after years as a television-era trickster; and the modern era (1988 to the present), anchored by The Killing Joke, the death of Jason Todd, and Scott Snyder's landmark arcs. On screen, Joaquin Phoenix's Joker (2019) grossed over one billion dollars worldwide, becoming the first R-rated film in history to reach that milestone.

This guide sticks to the verifiable: eBay medians from our estimator (eBay.fr + eBay.com, June 2026) and records documented by Heritage Auctions, ComicLink, and the specialist press. Batman #1 returns an eBay median of €7 across 100 listings, but that figure is dominated by modern reprints and facsimile editions — it bears no relation to the value of an original 1940 copy (a multi-million-dollar grail). Only documented auction records are cited for that issue.

The two Golden Age grails fall outside our eBay estimator; the figures cited for them are exclusively documented auction records. The eBay median for Batman #251 (65 listings) is reliable for the mass market, but reflects copies of all grades combined.

Batman #1 (1940): the ultimate Golden Age grail

Published in Spring 1940, Batman #1 is one of the most significant comics ever printed: it is the first appearance of both the Joker and Catwoman (listed in the issue simply as "The Cat"). The Joker is introduced immediately as a killer — a grinning, calculating criminal mastermind. His creation is credited to Bill Finger (script), Bob Kane (art), and Jerry Robinson, whose playing card inspired the character's facial design. This issue is a five-figure grail at mid grades and a seven-figure grail in high grade: the sole CGC 9.4 copy known realised $2.22 million at Heritage Auctions in January 2021, setting the absolute record for the title. Our eBay estimator returns a median of €7 across 100 listings, but that figure is entirely dominated by facsimile editions and modern reprints — it does not reflect what an original 1940 copy commands, which can exceed $10,000 even in very low grade.

Detective Comics #168 (1951): the origin behind the Red Hood

Published in February 1951, Detective Comics #168 gave the Joker a mythology. "The Man Behind the Red Hood!", scripted by Bill Finger, reveals that the Joker was once an ordinary lab worker who adopted the Red Hood alias to carry out a robbery at the Ace Chemical plant. Cornered by Batman mid-heist, he plunged into a vat of chemicals and emerged with chalk-white skin and a permanent rictus grin — the Joker was born. This origin story directly influenced The Killing Joke (1988) and the 1989 film. Our estimator returns only 4 eBay listings — far too few for a reliable median. The market reference remains auction rooms: a CGC 9.4 copy sold for $324,000 in 2022; a CGC 6.0 copy changed hands for $23,345 in March 2022.

Batman #251 (1973): the Bronze Age turning point

Published in September 1973, Batman #251 is the definitive Bronze Age Joker key. Denny O'Neil's script for "The Joker's Five-Way Revenge!" depicts the Joker methodically murdering former accomplices with cold-blooded efficiency — an abrupt end to the campy prankster persona the character had acquired during the television era. Neal Adams's cover, the Joker looming large in the foreground opposite Batman, has become one of the most iconic images in the medium's history. Our estimator returns a median of €9 across 65 listings — a solid signal for the entry-level market. In high grade, the CGC 9.8 record stands at $38,000, set at ComicLink's June 2024 focused premium auction. Among the historically significant Joker keys, this is the most accessible.

Batman: The Killing Joke (1988) and A Death in the Family

Batman: The Killing Joke (1988), written by Alan Moore and drawn by Brian Bolland, is the character's creative apex: in a single night, the Joker shoots and paralyses Barbara Gordon and subjects Commissioner Gordon to psychological torture. The story deepens the origin established in Detective Comics #168 — an ordinary man tipped into madness by one catastrophic day. The first softcover printing is plentiful; a CGC 9.8 copy currently trades between $150 and $250 according to recent market data. Our estimator does not cover this graphic novel series. In the same year, Batman #426–429 ("A Death in the Family", 1988–1989) saw the Joker beat Jason Todd — the second Robin — to death with a crowbar, with readers deciding the outcome by phone vote. Batman #429, the concluding chapter, returns a median of €28 across 32 listings via our estimator.

Building your collection: a strategy by budget

On a limited budget, Batman #251 (median €9) is the ideal historical entry point — a genuine key at a mass-market price. With a mid-range budget of €100–500, the "A Death in the Family" arc issues in solid condition, or an ungraded first printing of The Killing Joke, offer excellent value relative to their importance. The Golden Age grails — Batman #1 and Detective Comics #168 — are five-to-seven-figure acquisitions best pursued through Heritage Auctions, ComicLink, or Comic Connect, always with CGC or CBCS certification. Whatever your target, condition is decisive: a single grade point difference can double or triple the value on major keys.
