Quarter Century Secret Rare (QCSR) is a Japanese OCG foil finish that stood in for the game’s regular top-tier secret rare between April 2023 and early 2025 — and the rarity it stood in for, Prismatic Secret Rare, is back on current Japanese boxes today. If a Secret Rare in your binder has a champagne-gold, speckled name and a small anniversary watermark, that’s QCSR. Without that watermark, do not identify the card as Prismatic from the watermark alone; compare the foil pattern described in the ladder below.
The OCG’s foiling ladder has kept growing since Quarter Century Secret Rare was introduced, most recently with a serial-numbered “Grand Master Rare” tier debuting in February 2026 that has nothing to do with the Quarter Century era despite the similar top-of-the-set feel. This guide lays out where the OCG’s main current rarity tiers sit on that ladder, walks through exactly when Prismatic Secret Rare and Quarter Century Secret Rare traded places, and shows where these finishes actually turn up in Japanese product.
Quarter Century Secret Rare (QCSR) launched in Japan in February 2023 and officially replaced Prismatic Secret Rare from Duelist Nexus (April 2023) to Alliance Insight (January 2025) — after which Prismatic Secret Rare returned as the OCG’s standard secret-rare foil, and remains the current finish on releases such as the LOCR Limit Over Collection: The Rivals booster box (currently listed at ¥7,455, ~$47). The dedicated QCSR showcase set, Quarter Century Art Collection, is listed on our site without a displayed price, with sourcing handled through Quick Order.
Yen figures below convert at ¥159/USD (September 2026). All dates and set specs are the official Japanese OCG release information for the products named.
A Practical OCG Rarity Ladder, Foil by Foil
OCG rarity is a foiling hierarchy, not a distribution guarantee — a tier tells you how a card is printed, not how many cards of that print exist in a given box. The core ladder runs from plain card stock up through increasingly elaborate foil treatments, and several specialty tiers sit on top of that base run.
| Tier | Foil treatment |
|---|---|
| Normal / Normal Rare | No foil, or a plain foil card name only — the base finish. |
| Rare | Silver or black-foil letters on the card name. |
| Super Rare | Holofoil background behind the artwork. |
| Ultra Rare | Gold holofoil letters on the card name, combined with a holofoil background. |
| Ultimate Rare | Embossed gold holofoil texture running across the name, artwork and borders. |
| Secret Rare | Rainbow holographic letters on the card name. |
| Prismatic Secret Rare | A Secret Rare variant with a horizontal/vertical foil pattern and multiple speckled holofoil colours in the name (detailed below). |
| Quarter Century Secret Rare | A time-limited OCG variant of the Secret Rare foil with a champagne-gold speckled name and a 25th-anniversary watermark (detailed below). |
| Grand Master Rare | A serial-numbered top tier introduced in 2026, applied to a fixed subset of a set’s Ultra Rares (detailed below). |
The three specialty tiers covered in depth below are Prismatic, Quarter Century and Grand Master.
Quarter Century Secret Rare: What the Foil Actually Is
Quarter Century Secret Rare is identified by a speckled holographic champagne-gold card name and a small “Yu-Gi-Oh! Card Game 25th Quarter Century” watermark printed in the text box. It was introduced in the Japanese OCG’s Rarity Collection Quarter Century Edition in February 2023, created specifically to mark the OCG’s 25th anniversary of its original February 4, 1999 Japan launch.
Foil-wise, QCSR is nearly identical to the OCG’s earlier “20th Secret Rare” finish, differing mainly in the watermark and the exact name-foil colour. It is not a permanent addition to the ladder — it functioned as a time-boxed replacement for the OCG’s regular top secret-rare foil, which is the relationship the next section walks through in full.
Prismatic Secret Rare: The Rarity QCSR Replaced — Twice
Prismatic Secret Rare and Quarter Century Secret Rare occupy the same “top OCG secret rare” slot at different points in time — they are not two rarities that coexist on the same set. Whichever one is printed on a given release depends purely on which month that set came out in Japan.
Prismatic Secret Rare is a Secret Rare variant where the holographic foil follows a horizontal and vertical parallel pattern, instead of the diagonal pattern used on a standard Secret Rare, and the card name carries multiple speckled holofoil colours rather than one solid colour. In the OCG specifically, Prismatic Secret Rares visually resemble the TCG’s Starlight Rare cards.
The finish has moved on and off the OCG’s top slot several times:
| Date (Japan) | Release | What changed |
|---|---|---|
| April 2020 | Rise of the Duelist | The OCG’s “20th Secret Rare” finish is replaced by Prismatic Secret Rare. |
| February 2023 | Rarity Collection Quarter Century Edition | Quarter Century Secret Rare is introduced. |
| April 2023 – January 2025 | Duelist Nexus to Alliance Insight | Quarter Century Secret Rare officially replaces Prismatic Secret Rare as the OCG’s standard top secret-rare foil. |
| April 2025 | Special Blue-Eyes White Dragon ukiyo-e framed set | Quarter Century Secret Rare’s last confirmed Japanese appearance to date. |
| March 2025 onward | Deck-Build Pack: Justice Hunters and later, including LOCR (March 2026) | Prismatic Secret Rare returns as the OCG’s standard top secret-rare foil. |
In other words: a missing champagne-gold name and 25th-anniversary watermark alone does not establish that a current-era Japanese secret rare has the Prismatic finish. Compare its foil pattern with the Prismatic treatment described above.
Where QCSR Actually Shows Up: Quarter Century Art Collection
Quarter Century Art Collection (QCAC) is the OCG booster built specifically to showcase the Quarter Century Secret Rare finish. It released in Japan on February 22, 2025, with 100 cards across the set, packed 4 cards per pack, 15 packs per box.
Secret Rare and Quarter Century Secret Rare availability in QCAC varies by card. The set also introduced brand-new artwork exclusive to these prints — including a third artwork for Dark Magician Girl, and new artworks of Blue-Eyes White Dragon and Dark Magician that exist only as Quarter Century Secret Rares.
The three photos above show the Ultra Rare and Super Rare base prints from the set; the Quarter Century Secret Rare versions of Blue-Eyes White Dragon and Dark Magician carry the different artwork noted above rather than being a foil-only variant of these exact images.
The Newest Tier: Grand Master Rare (Not a Quarter Century Rarity)
The Grand Master Rare tier debuted in Limit Over Collection: The Heroes, released in Japan on February 28, 2026. Its companion release three weeks later, Limit Over Collection: The Rivals (LOCR), released in Japan on March 20, 2026, carries the same tier: LOCR is packed 4 cards per pack, 15 packs per box, for 80 total cards in the set (38 Ultra Rare, 42 Super Rare). All 80 cards are also available as Prismatic Secret Rare and as Secret Rare — the same Prismatic finish that returned to the OCG’s standard secret-rare slot the year before.
LOCR’s share of that addition is Grand Master Rare: a serial-numbered treatment officially described as “100 cards limited with unique serial numbers,” applied to only 18 of the set’s 38 Ultra Rares. The set also carries an “Extended Art” frame-breaking design, available as both Ultra Rare and Prismatic Secret Rare.
Grand Master Rare is a distinct rarity from a later, unrelated set — it is not a Quarter Century-era rarity, is not related to QCSR, and its serial-numbered treatment shouldn’t be confused with the champagne-gold QCSR foil described above.
One More Identification Detail: Card Backs by Region
Rarity foil isn’t the only way to place an OCG card. Unlike the TCG, which prints one universal card back logo worldwide, OCG card backs differ by region — Japanese, other-Asian and Korean releases each carry their own back design. If you’re trying to confirm whether a card in hand is a Japanese OCG print rather than another region’s OCG release, the back is worth checking alongside the rarity foil itself.
Buying Into These Rarities from Japan
Both current-generation sets discussed here connect directly to what’s on our site right now. The Prismatic Secret Rare finish that has returned to the OCG’s standard slot is what ships inside LOCR Limit Over Collection: The Rivals, currently listed at ¥7,455 (~$47), alongside its Grand Master Rare and Secret Rare prints. For the Quarter Century Secret Rare finish itself, the dedicated showcase product is the Quarter Century Art Collection booster box (carton), which is listed on our site without a displayed price — sourcing for it goes through Quick Order.

Frequently Asked Questions
What is a Quarter Century Secret Rare in Yu-Gi-Oh?
Quarter Century Secret Rare (QCSR) is a Japanese OCG foil finish with a speckled holographic champagne-gold card name and a “Yu-Gi-Oh! Card Game 25th Quarter Century” watermark in the text box. It launched in February 2023 with Rarity Collection Quarter Century Edition to mark the OCG’s 25th anniversary, and officially served as the OCG’s standard top secret-rare foil from April 2023 to January 2025.
What’s the difference between Quarter Century Secret Rare and Prismatic Secret Rare?
They occupy the same “top OCG secret rare” slot at different times rather than existing side by side. Prismatic Secret Rare uses a horizontal/vertical foil pattern with multiple speckled holofoil colours in the name; Quarter Century Secret Rare uses a champagne-gold speckled name plus the 25th-anniversary watermark. Prismatic was the OCG’s standard finish before April 2023, was replaced by QCSR from April 2023 to January 2025, and has been the standard finish again since March 2025.
Is Grand Master Rare part of the Quarter Century Secret Rare family?
No. Grand Master Rare is a separate, later rarity introduced in February 2026 with Limit Over Collection: The Heroes and carried into its companion set, Limit Over Collection: The Rivals (March 2026). It’s a serial-numbered treatment applied to only 18 of LOCR’s 38 Ultra Rares, and it has no connection to the Quarter Century Secret Rare foil or the 25th-anniversary watermark.
Where can I find Quarter Century Secret Rare cards?
The dedicated showcase set is Quarter Century Art Collection (QCAC), a 100-card Japanese OCG booster released February 22, 2025. Secret Rare and Quarter Century Secret Rare availability varies by card, and some artworks are QCSR-exclusive.
Do Prismatic Secret Rare cards look different in the TCG than in the OCG?
Yes. In the OCG, Prismatic Secret Rares visually resemble the TCG’s Starlight Rare cards rather than the TCG’s own Prismatic Secret Rare treatment, so a card labelled the same way in each region doesn’t necessarily look identical.
How can I tell if a card is a Japanese OCG print rather than another region’s release?
Alongside the rarity foil itself, check the card back. The TCG uses one universal card-back logo worldwide, but the OCG prints different card backs for Japanese, other-Asian and Korean releases, which is a useful secondary check when identifying a print.
