Kouzuki Oden EB01-001 price spike: Why did the price increase 2251%?
If you have been monitoring the One Piece Card Game secondary market over the last week, you have likely noticed a massive, eye-watering surge in the value of certain Japanese promotional and specialty cards. As of May 15, 2026, the market is experiencing extreme volatility, characterized by astronomical percentage gains in high-rarity Japanese promos and significant corrections in several English and Japanese singles.
In this report, we break down the specific price movements, the distinction between raw and graded copies, and what these shifts mean for your collection.
The Massive Surge: Kouzuki Oden EB01-001 and the Japanese Promo Boom
The most staggering movement in the market today is undoubtedly Kouzuki Oden EB01-001 from the One Piece Japanese Extra Booster Memorial Collection. In a single 7-day window, the price of an ungraded copy of this card skyrocketed from $2.00 to $47.03—a staggering 2251.5% increase.
While such a vertical move often signals a supply shortage or a sudden influx of demand for the Memorial Collection era, it is important to note the ceiling for high-grade collectors. For those holding BGS 10 copies, the value sits at approximately $42.50, suggesting that the current market frenzy is primarily driven by the sudden movement of raw, ungraded specimens.
Is Monkey.D.Luffy P-055 [College Basketball US Voyage] still going up?
Not to be outdone by the Oden surge, Monkey.D.Luffy [College Basketball US Voyage] P-055 (One Piece Promo) has seen a massive 60.76% jump, moving from $195.95 to $315.00 in the last seven days.
This is not a one-day blip; this card has established a strong upward trajectory. When we look at the graded market for this specific Luffy promo, we see a massive "PSA 10 Premium." While an ungraded copy is currently $315, a PSA 10 copy is commanding a massive $816. This indicates that while the raw market is moving, the true value is heavily concentrated in pristine, gem-mint specimens. If you are looking at the mid-tier grades, the gap narrows significantly: a PSA/B/BGS 9 copy is priced at $191.39, and a BGS 10 copy sits at an incredible $1061. The sheer spread between the $315 raw price and the $1061 BGS 10 price suggests that collectors are aggressively chasing perfection for this specific promo.
Monkey.D.Luffy P-007 [Championship 2023] price trend analysis
The movement for Monkey.D.Luffy [Championship 2023] P-007 (One Piece Promo) shows a sustained multi-week climb. Looking at the 30-day history, the card was sitting at $39.98 on May 4th (a 49.51% increase from its previous baseline). In the most recent 7-day window, it has surged again by 103.85% to reach $81.50.
This is a classic "stair-step" upward trend. Interestingly, the graded market for P-007 does not mirror the massive premiums seen in the College Basketball promo. For example, a PSA/BGS 9 copy is valued at $28.23, which is actually lower than the current ungraded price of $81.50. This often happens when a sudden spike in raw demand outpaces the arrival of new graded supply, or when the current "ungraded" price is being driven by a temporary scarcity of loose cards.
Premium Card Collection [Live Action Edition] price explosion
Another extreme outlier is the Premium Card Collection [Live Action Edition] (One Piece Japanese Promo). This card has seen a 1220.29% increase, jumping from $3.40 (as of May 5th) to $44.89 today. This is a massive recovery from its recent low, where it had dropped 22.9% earlier in the month. This type of movement is typical for niche Japanese promos where a sudden resurgence in interest or a localized shortage can trigger a massive percentage swing from a very low base price.
Is the Monkey.D.Luffy ST16-005 price increase sustainable?
For those looking at the Monkey.D.Luffy [Beginners Deck Party Winner] ST16-005 (One Piece Starter Deck 16: Uta), the news is steadily positive. The card has risen 27.81% in the last week, reaching $158.50. Unlike the extreme volatility seen in the Oden or Live Action promos, this move is more measured, suggesting a steady increase in demand for the ST16 winner prize cards.

The Market Corrections: What’s causing the price drops?
While the promos are soaring, the "Top Losers" list shows a significant cooling off for several English and Japanese staples.
Monkey.D.Luffy OP07-091 [Offline Regionals] price drop explained
The most significant decline in terms of raw dollar value is Monkey.D.Luffy [Offline Regionals] OP07-091 (One Piece 500 Years in the Future). The card has dropped 28.96%, falling from $210.92 to $149.84.
Unlike the lower-value cards, the high-end graded market for this Luffy remains extremely expensive, suggesting the "crash" is primarily affecting the raw/ungraded market. For collectors of "perfection," the numbers remain astronomical: a BGS 10 copy is priced at $2025.71, and a PSA 10 is at $482.50. The drop to $149.84 for ungraded copies suggests that while the "ceiling" for top-tier grades remains intact, the liquid, ungraded market is currently undergoing a significant correction.
Usopp OP10-014 and the Japanese Royal Blood slump
Usopp OP10-042 (One Piece Japanese Royal Blood) has seen a sharp decline of 46.51%, dropping from $13.74 to $7.35. This downward movement is reflected across the graded spectrum as well; for instance, a PSA 10 copy has fallen to $29, and a BGS 10 copy is at $30. When the price drops this significantly across both raw and graded sectors, it usually indicates a broad reduction in market interest for that specific set's secondary value.
Why is the Sealed Promotion Pack Vol. 3 losing value?
The Sealed Promotion Pack Vol. 3 (One Piece Japanese Promo) has fallen 36.32%, moving from $11.59 to $7.38. As a sealed product, this movement often reflects a change in the availability of new promotional waves or a shift in how collectors are valuing older sealed Japanese stock.
Yamato ST09-012 and Belo Betty OP05-002 price declines
Two other notable drops include Yamato ST09-012 (One Piece Starter Deck 9: Yamato), which fell 40.16% from $9.96 to $5.96, and Belo Betty OP05-001 (OP05) from the One Piece Card Game, which dropped from a previous high to its current state, representing a significant decline. Specifically, the trend for Belo Betty-related assets has seen a downward correction, with the card's value moving away from its previous peaks.
For the Yamato card, the drop is notable because the current price of $5.96 is approaching the floor for standard starter deck-related cards, suggesting a period of price stabilization.
