Diglett, Sideways Fighting Symbol
- Set
- Base Set · 47/102
- Released
- 1999 (English)
The smallest mistake on this list is a single energy symbol turned on its side. On a short print run of Base Set Diglett, the Fighting symbol beside the Dig attack came out rotated 90 degrees, a flaw traced to the Unlimited 2-Player Starter Set boxes. PSA recognizes the variant on its labels, and a PSA 10 copy sold on eBay in January 2023 for $199.99, the record for this error.
Butterfree “d” Edition Error
- Set
- Jungle · 33/64 · 1st Edition
- Released
- 1999 (English)
An ink bubble settled over the 1st Edition stamp on a run of Jungle Butterfree and turned the 1 into a lowercase d, and the hobby has called it the d Edition ever since. Bulbapedia counts it among the most common errors Wizards of the Coast ever shipped, with well over 100 copies in circulation, so the money stays modest. The highest PSA 10 sale we could open and verify is $390 on eBay in December 2022, even though PriceCharting’s market level for the grade has since climbed near $720.
Blastoise “Stage” Error
- Set
- Base Set · 2/102
- Released
- 1999 (English)
The instructions at the top of this card tell you to put Blastoise on the 1 card. The word Stage never made it onto the plate, and PSA documents the omission in its official error guide. What keeps this entry low is the paper trail. Every PSA-logged sale of the error sits in the hundreds, topped by a PSA 8 at $475 on eBay in July 2020, and no high-grade record has surfaced to challenge it. The card is famous. Its documented sales are thin, and this list prices paper trails, not fame.
Dark Persian, No HP Error
- Set
- Black Star Promo · 17 · Nintendo Power Insert
- Released
- 2000 (English)
This Dark Persian came free inside Nintendo Power magazine in 2000, and a few copies reached subscribers with nothing at all in the HP corner, just the name and the type symbol where 60 HP should sit. PSA recognizes both the error and the corrected printing in its error guide. The error’s verified top is a PSA 9 at $640 on eBay in April 2025. Keep the figure in perspective, because the corrected version of this same promo is the one with the five-figure prices, including a $48,000 PSA 10 at Fanatics Collect in October 2026, and none of that money belongs to the error.
Wartortle, Evolution Box Error
- Set
- Base Set · 42/102
- Released
- 1999 (English)
Every Wartortle card tells you it evolves from Squirtle. On a short Unlimited print run, the little portrait in the evolution box shows Wartortle itself, a turtle evolving from itself. The error never reached the 1st Edition or Shadowless runs, and every Portuguese printing of the card carries it, which points to one shared print facility. A PSA 9 copy sold on eBay in January 2026 for $999.99, a single cent short of four figures.
Ghost Stamp Pikachu
- Set
- Base Set · 58/102 · Shadowless 1st Edition
- Released
- 1999 (English)
The 1st Edition stamp on this Pikachu barely printed at all. What remains is a pale outline reading E ITION, with the 1 and the D missing, on yellow-cheeks Shadowless copies that surfaced inside gold-strip Zap! theme decks. Collectors named it the Ghost Stamp, and CGC labels it that way on its slabs. A BGS 9 copy sold on eBay in March 2026 for $2,000, matching the $2,000 that PSA 9 copies reached back in May 2022.
Ancient Mew, “Nintedo” Error
- Set
- Movie Promo · Ancient Mew I (Japanese)
- Released
- 1999 (Japanese)
The first Japanese printing of the Ancient Mew movie promo misspells the company that made the game. The copyright line along the bottom reads Nintedo, one n short, and corrected printings followed once the mistake was caught. Unlike most of this list, the error is not rare. PSA’s population for the error in PSA 10 alone runs to roughly 800 copies. Fame does the work instead, and a PSA 10 sold on eBay in October 2026 for $6,500.
No Damage Ninetales
- Set
- Base Set · 12/102 · Shadowless
- Released
- 1999 (English)
Fire Blast is supposed to hit for 80. On some Shadowless copies of Ninetales, the damage number was never printed at all, leaving the attack cost and text beside an empty space. The error is tied to the Shadowless Brushfire theme decks, and PSA’s error guide documents it. The record rests on collector documentation of a 2021 PWCC auction, where a PSA 9 reached $8,170 and a second PSA 9 changed hands at $8,000 the same night. It is the one record on this list we flag as softer than the rest, because PSA’s own price archive does not break this error out under its own label.
Dark Dragonite, No-Holo Error
- Set
- Team Rocket · 5/82
- Released
- 2000 (English)
Team Rocket printed Dark Dragonite twice, as the holo rare at number 5 and as a plain rare at number 22. Some number 5 copies came off the press with no holofoil at all, the holo card’s layout rendered completely flat. Bulbapedia traces the error to the design stage of the 1st Edition run, and it was never corrected, so Unlimited copies carry it too. A PSA 10 1st Edition copy sold at Goldin in March 2026 for $73,200, and an Unlimited PSA 10 brought $34,100 on eBay the following month.
Prerelease Raichu
- Set
- Base Set · 14/102
- Released
- 1999 (English)
The most famous error card in the hobby started as a factory accident. A small number of Base Set Raichu came away from the press run with the word PRERELEASE stamped across the artwork, a stamp meant for the Jungle prerelease Clefable that was never intended for a Base Set card. Wizards of the Coast denied the card existed for years before confirming it, and it has been the grail of error collecting ever since. In October 2026 a copy graded PSA 5 sold through Alt for $699,625, the record for any Raichu and more than the other nine cards on this list have ever made combined, several times over. A PSA 6 had already brought $640,500 at Goldin in August 2026 and $555,000 at Heritage in September 2025.

Honorable mentions
- Aerodactyl (Fossil) Prerelease. The other famous prerelease stamp is not on this list, on a technicality. Aerodactyl’s PRERELEASE stamp was applied on purpose, to the right card, for the Fossil prerelease, which makes its copies deliberate promo variants rather than factory errors. The sales are real, including a PSA 10 at $1,842 on eBay in July 2025, a figure that would have placed it sixth here. If your definition of an error card includes it, slot it in at number 6 and push everything below it down one.
