Grading math for this card
Prefilled with the latest qualifying sale for each grade where one exists. Replace any value with your own. We never suggest what grade your copy will get.
Compare grading math across cards · Formula from Grading: condition, uncertainty, and economics: grading pays only if your honest chance of the high grade exceeds (raw net + cost − other-outcome net) ÷ (high-grade net − other-outcome net). The 13% fee is an editable assumption, not a quoted tariff.
About Gate Guardian
Gate Guardian is the Secret Rare card numbered MRD-000 in the original English Metal Raiders release. Collectors search for it because it is a high-profile early monster with a front-of-set number and many later lower-rarity substitutes.
Why this card matters
Verified factGate Guardian matters as an early Secret Rare monster from Metal Raiders and as a card tied to the Sanga, Kazejin, and Suijin theme. Konami's database records the 2002 MRD-000 Secret Rare printing and separates later Dark Legends, Retro Pack, Speed Duel, Maze of Memories, and LC01 entries. The original MRD-000 card is the collectible version tracked here. [1]
Identifying the exact version
Verified factThe primary identifier is MRD-000. The 2023 LC01 reprint uses MRD-EN000 and should not be combined with 2002 MRD-000 sales. For edition, check the 1st Edition text and security foil color: Konami says First Edition and Limited Edition use gold security foils, while Unlimited uses silver. Secret Rare finish also needs to match the card, not merely the name. [1][2]
What moves the price between versions and grades
AnalysisThe opened PSA records show separate PSA 10, 9, 8, 7, and lower-grade transactions for 1st Edition MRD-000. Grade, cert, and sale venue matter because a PSA 10 comp is not interchangeable with a raw copy or lower grade. Reverse-foil or error claims require their own photo evidence and should not be blended into normal Secret Rare comps. [3]
Authenticity checks
Verified factCompare against official references; multiple checks; no destructive tests; copied cert numbers exist. Confirm MRD-000, Secret Rare finish, edition text, security foil color, monster stats, back design, card stock appearance, and seller-owned images. For slabbed copies, match the cert record, but remember PSA warns that checking a valid cert number does not by itself prove the listed physical slab is genuine. [1][2][5]
Telling the versions apart
| Version | How to identify it |
|---|---|
| MRD-000 1st Edition Secret Rare | Printed as MRD-000, Secret Rare, with 1st Edition text and a gold security foil. |
| MRD-000 Unlimited Secret Rare | Printed as MRD-000, Secret Rare, no 1st Edition text, and a silver security foil. |
| MRD-EN000 LC01 25th Anniversary Secret Rare | Modern 2023 reprint with MRD-EN000 set code from Metal Raiders (LC01 25th Anniversary Edition). |
| Reverse Foil Error reported variant | Treat as unverified unless the listing supplies clear front, angle, and provenance photos; no official source confirming this variant was found for this batch. |
