The auction record for an original Batman #1 (1940) exceeds $2,200,000 (CGC 9.4, Heritage Auctions, January 2021). Our eBay estimator currently shows a median of €7 across 100 listings for the Batman series at issue #1 — but that figure is dominated by official DC facsimile editions released in 2023 and 2025, not the 1940 original. Knowing the difference is one of the most important skills a Joker comic collector can develop.

The Joker, co-created by Bill Finger, Bob Kane, and Jerry Robinson, first appeared in Batman #1 (Spring 1940). Since then, his key issues have been officially reprinted, collected, and facsimile-republished dozens of times. Those editions flood the secondary market and can mislead buyers who do not know what to look for. This guide walks through the identification signals for each major Joker key, backed by verified market data.

All figures in this guide are sourced from our eBay estimator (eBay.fr + eBay.com, June 2026) when listing counts exceed the 15-listing reliability threshold, and from documented auction records at Heritage Auctions, ComicLink, and specialist press for books too rare or whose eBay median is contaminated by reprints.

Batman #1 (1940): the facsimile trap

Batman #1 (Spring 1940) is the ultimate Joker grail: it contains the first appearance of the Joker (and Catwoman), written by Bill Finger with art by Bob Kane and Jerry Robinson. A CGC 9.4 copy sold for $2,220,000 at Heritage Auctions in January 2021 — the world record at the time. A private sale involving the same copy was later reported at $6,000,000. A CGC 8.0 had previously sold for approximately $498,000 in 2019. None of these figures bear any relation to the €7 median our estimator shows across 100 eBay listings: that pool is almost entirely made up of DC's official facsimile editions published in November 2023 and November 2025, which retail new at $7.99–$8.99.

How to identify the real thing. A genuine 1940 Batman #1 has yellowed (often brown) paper, uneven margins typical of period offset printing, interior advertisements for 1940s products (toys, cereal, early DC subscriptions), and a cover price of 10 cents printed on the front cover. Recent DC facsimiles have modern white or lightly off-white paper, cleaner margins, and explicitly state "Facsimile Edition" on the back cover or an interior page. The 2025 Golden Age-format edition reproduces the oversized period dimensions but remains a reproduction. For any significant purchase, always require documented provenance and, ideally, a CGC or CBCS holder.

Detective Comics #168 (1951): the Joker's origin, too rare for eBay

Detective Comics #168 (February 1951) contains the first-ever origin of the Joker: "The Man Behind the Red Hood" reveals that the Clown Prince of Crime was once a masked criminal whose face was hideously disfigured in a vat of chemicals — the mythology that Alan Moore would later build on in The Killing Joke. Our eBay estimator returns only 4 listings for this issue — far too thin to quote a reliable median. For documented auction records: a CGC 9.4 (white pages) copy sold for $324,000 in November 2022 according to Heritage Auctions data. Mid-grade copies (CGC 4.0 to 6.5) typically trade between roughly $1,500 and $15,000 based on Heritage and ComicLink data. No facsimile edition of this issue has been published. The rarity is genuine — never accept an eBay price for this book without verifying the actual condition and grading certification.

Batman #251 (1973): the Bronze Age comeback

Batman #251 (September 1973), written by Denny O'Neil and drawn by Neal Adams, is the issue that restored the Joker as a genuine murderer after years of campy television-era softening. "The Joker's Five-Way Revenge!" and its iconic Adams cover have become the defining image of the modern Joker. Our estimator returns a reliable median of €9 across 65 listings — a valid signal for the entry-level market. That figure reflects all grades combined: in high-grade CGC, a 9.8 copy sold for $38,000 in June 2024 according to CGC market data. No official DC facsimile of this issue exists as of June 2026. The low-priced eBay listings are genuine ungraded copies in mid-to-low condition, not reproductions.

Batman: The Killing Joke (1988): 14 printings, one that matters

Alan Moore and Brian Bolland's Batman: The Killing Joke (1988) is probably the most frequently misidentified Joker book among newer collectors. It has been through at least 14 printings as a single issue, and also exists as a hardcover, a Deluxe Edition, and in collected form. The identification method is straightforward: look at the colour of the title lettering on the cover. The first printing (1988) has neon green embossed lettering. The second printing has pale pink lettering. Subsequent printings cycle through yellow, orange, blue, dark orange, light yellow, light blue, and crimson. All early printings shared the $3.50 cover price.

PrintingTitle letter colourCGC 9.8 price range
1st printing (1988)Neon green embossed$150 – $250 (2026 market)
2nd printingPale pinkLow (tens of dollars)
3rd through 14th printingsYellow, orange, blue, etc.Nominal value only

In practice: a first-printing CGC 9.8 currently sells for $150 to $250 based on early-2026 market data — a meaningful premium over later printings. If a seller does not specify the printing, ask for a clear cover photo and check the title colour before committing to a purchase.

Batman #426–429 (1988): "A Death in the Family"

The "A Death in the Family" arc (Batman #426 to #429, 1988), in which the Joker murders Jason Todd (the second Robin), is one of DC's most requested runs. Our estimator returns thin listing counts for some issues in the arc: #426 (11 listings) and #428 (12 listings) fall below the reliability threshold for quoting a precise median. Batman #427 returns a median of €21 across 16 listings and #429 a median of €28 across 32 listings — both usable for entry-level reference. No official facsimile editions exist for these issues. Low-priced eBay copies represent genuine ungraded mid-grade copies, not reproductions. One common issue to watch for: undisclosed pressing (professional cleaning and flattening of a book to improve its apparent grade) is widespread in this era and is invisible without a loupe or independent certification.

Practical rules for ungraded purchases

For Golden Age keys (Batman #1, Detective Comics #168), never pay more than a few dozen euros for an uncertified copy without an in-person expert assessment or a professional grading submission. For The Killing Joke, the title colour is your first filter — visible in any cover photograph. For Bronze and Modern keys (Batman #251, #426–429), official reprints are rare, but undisclosed pressing is common. When in doubt, CGC or CBCS certification is the most reliable protection available to the modern collector.
