For Detective Conan fans, the launch of an official trading card game in 2024 marked a long-awaited moment. The CT-P01 “Detectives’ Trump Card” set introduced collectors to a properly licensed TCG built around one of Japan’s most enduring mystery franchises, and the SEC (Secret Rare) tier cards quickly became chase items across the Japanese hobby scene. The P001 signed variant featured here sits at the very top of the rarity ladder, combining the secret rare treatment with autograph-style printing that has driven secondary market interest since release.
Japanese trading cards occupy a unique space in the global collectibles market. Print runs are typically smaller than Western equivalents, card stock and foil treatments tend to be higher quality, and signed or promotional inserts are often distributed only through Japanese retail channels and convention events. That means a card like this CT-P01 SEC P001 rarely circulates internationally in any meaningful quantity, making sourcing directly from Japan the most reliable route for serious collectors.
About This Item
This listing is for the Detective Conan CT-P01 Detectives’ Trump Card SEC P001 signed card, released by Takara Tomy in 2024 as part of the inaugural set for the official Detective Conan Trading Card Game. The CT-P01 set, titled “Detectives’ Trump Card” (探偵たちの切り札), launched the franchise’s standalone TCG and featured a wide roster of characters from the long-running manga and anime, including Conan Edogawa, Kaito Kid, Heiji Hattori, Ran Mouri, and the Detective Boys. The SEC (Secret Rare) classification represents the highest pull tier in the set, sitting above SR and RRR cards in terms of scarcity.
The P001 designation marks this as the first promotional/signed variant in the series numbering, which traditionally carries additional prestige in Japanese TCG circles. Cards in this tier feature premium foil treatments, full-art illustrations, and printed signature flourishes designed to mimic an autograph layer over the artwork. This particular piece is offered in pre-owned condition, having been carefully inspected for centering, surface condition, and edge integrity before listing, and it is shipped from Japan with tracking.

The Detective Conan Franchise: Why Collectors Care
Detective Conan, known internationally as Case Closed, began serialization in Weekly Shōnen Sunday in 1994 under the pen of Gosho Aoyama. Over three decades later, the manga has surpassed 100 volumes, the anime continues to air weekly, and the annual theatrical films routinely top Japan’s box office charts. The 2024 film “The Million-Dollar Pentagram” became one of the highest-grossing entries in the entire franchise, which helped fuel anticipation for the TCG launch in the same year.
What sets Detective Conan apart from many shōnen-era franchises is the consistency of its fanbase. The series spans generations of readers in Japan, with merchandise demand driven by both nostalgic adult collectors and current viewers. This translates into strong, sustained interest in licensed goods — figures, plush, stamps, and especially cards. Prior to the 2024 TCG, Detective Conan had appeared in collaboration sets with other card games, but never as the centerpiece of its own dedicated game. That made CT-P01 a landmark release.
Rarity and Value Factors
SEC cards in the Detective Conan TCG are pulled at extremely low rates per booster box, with signed P-series promos representing an even smaller subset. Value on the Japanese secondary market is driven by several converging factors: character popularity (Conan, Kaito Kid, and Shuichi Akai cards command premiums), print quality and centering, surface condition of the foil layer, and whether the card has been graded by services like PSA or BGS. Because the set is recent, ungraded high-grade copies are still the dominant supply, but that is expected to shift as more collectors submit cards for slabbing. Early signed variants from inaugural sets historically appreciate well once the next expansion releases and pulls dry up.

Collector’s Guide: What to Look For
When evaluating a high-tier card like the CT-P01 SEC P001, the first thing to examine is centering. Japanese print runs are generally tighter than Western counterparts, but SEC cards with full-bleed art and foil layers can still exhibit slight off-centering that affects grading potential. Look at the borders top-to-bottom and left-to-right under good light. Next, inspect the foil surface for scratches, scuffing, or “print lines” — fine horizontal lines that can occur during the foil application process. These are factory defects, not damage, but they do impact resale value.
Edges and corners are the next priority. Even cards stored in sleeves can develop subtle whitening at corners if handled before sleeving. Use a loupe or a phone macro camera to check. Finally, examine the back of the card for any indentation, bend, or fingerprint residue. Cards shipped from Japan are typically packaged in top-loaders or semi-rigid holders, which protects them in transit but doesn’t guarantee perfection — always review provided photos carefully.

Condition Checklist
- Centering: Check borders on all four sides — critical for grading potential
- Foil Surface: Inspect for scratches, scuffs, and print lines under angled light
- Corners: Look for whitening or softening at all four corners
- Edges: Examine for chipping, dings, or wear from handling
- Packaging: Top-loader or sleeve presence indicates careful prior ownership
Price Guide
Pricing for the CT-P01 SEC P001 signed variant has fluctuated since release. Played or lightly handled copies have traded in the $40–$80 range on the Japanese market, while near-mint ungraded examples typically sit in the $100–$200 range depending on the character depicted. PSA 10 or BGS 9.5+ graded copies of popular characters have crossed $300 and continue to climb as graded population data stabilizes. The biggest price drivers are character (Conan and Kaito Kid lead), surface condition of the foil, and whether the card comes with original packaging or pull documentation.
Similar Items Worth Exploring
Collectors who pursue the CT-P01 set typically branch into several adjacent areas. The standard SR and RRR rarities from the same expansion offer more accessible entry points while maintaining set cohesion. Booster boxes and sealed display cases from CT-P01 also remain a popular hold, since unopened Japanese product tends to appreciate steadily. Beyond the TCG, Detective Conan has been featured in Weiss Schwarz crossover sets over the years, which appeal to TCG players who want competitive play options alongside collection value.
Outside of cards, Banpresto and Sega prize figures of Conan, Kaito Kid, and Ran are natural companions, as are the annual movie-themed merchandise drops timed to each new theatrical release. Promotional shitajiki (pencil boards), clear files, and theater-exclusive bromides from films like “The Million-Dollar Pentagram” round out a well-rounded Detective Conan collection.
Why Buy Japanese Collectibles from Japan?
Japanese collector culture places exceptional emphasis on preservation. Cards are sleeved immediately upon pull, stored in binders or top-loaders, and frequently kept away from light and humidity. This means pre-owned Japanese trading cards generally arrive in better condition than equivalent items sourced elsewhere. Beyond condition, many promotional cards — including signed P-series variants like this one — were distributed only through Japanese tournaments, magazine inserts, or retailer campaigns, meaning Japan remains the primary source for authentic copies.
Buying directly from Japan also reduces counterfeit risk, as Japanese hobby shops and resellers have established authentication norms built around domestic supply chains. Tracking-enabled international shipping has made the process straightforward for overseas collectors.
Summary
The CT-P01 Detectives’ Trump Card SEC P001 signed card is a notable entry point into the Detective Conan TCG era — an inaugural-set chase card from one of Japan’s most beloved franchises, produced by Takara Tomy in 2024. For collectors who value franchise history, rarity, and the craftsmanship of Japanese card printing, this piece offers genuine long-term appeal. Pre-owned, carefully inspected, and shipped from Japan, it represents the kind of cross-generational collectible that Detective Conan fans have been waiting decades to add to their binders.
