What makes OP-17 special?
OP-17 brings together some of the most famous characters from One Piece.
The focus is on characters such as Monkey D. Luffy, Shanks, Kaido, Charlotte Linlin, Edward Newgate, and Rocks D. Xebec.
For collectors, the large number of different premium cards is particularly interesting. In addition to classic Alternate Arts, the set contains special collector's rarities, Special Cards, Treasure Rares, and extraordinary DON!! variants.
Edward Newgate also appears as a Treasure Rare in the English version, for example.
This makes OP-17 appealing to both players and collectors looking for rare cards or factory-sealed booster displays.
Which are the Chase Cards from OP-17?
A Chase Card refers to a particularly rare or sought-after card that many collectors wish to pull from a set.
In OP-17, the focus is currently on premium versions of well-known One Piece characters.
Cards revolving around:
Monkey D. Luffy
Shanks
Kaido
Charlotte Linlin / Big Mom
Edward Newgate / Whitebeard
Rocks D. Xebec
are receiving particular attention.
In addition, there are special Manga and Premium Artworks as well as special DON!! Cards.
Since market prices can change very quickly directly after release, when evaluating, one should always compare actual sold cards and not just asking prices.
We will supplement this article with current market prices after the official release.
OP-17 Pull Rates: How good are the chances?
An important piece of information upfront:
Bandai does not publish official Pull Rates for OP-17.
All figures currently circulating online regarding OP-17 Pull Rates are therefore based on opened booster boxes and cases from the community.
A current analysis of more than 1,000 opened OP-17 packs estimates approximately:
approx. 7 Super Rares per Booster Box
Furthermore, very different premium hits were observed depending on the box. In the analyzed sample, individual boxes could contain approximately 1 to 4 higher-value hits.
However, especially for Alternate Arts, Manga Cards, and other particularly rare variants, the distribution is not guaranteed.
This means:
Just because a certain card was pulled in one case does not mean that the same card or type of card must be present in every case.
Therefore, anyone who wants a very specific Chase Card should always consider whether opening displays or directly purchasing the single card is more sensible.
How many boosters does an OP-17 Booster Box contain?
An English One Piece OP-17 Booster Box typically contains:
24 Booster Packs
An English booster contains:
12 cards
This means you get a total of 288 card slots per display, although numerous cards may appear multiple times.
Bandai explicitly states that due to the random composition, duplicate cards may occur, and opening a display does not guarantee a complete set.
Buy OP-17 English or Japanese?
For Swiss collectors, the question often arises whether to buy an English or Japanese OP-17 Booster Box.
Both versions can be interesting, but they sometimes pursue different collecting goals.
OP-17 English
The English version is particularly interesting for many Swiss and European collectors, as the cards are widely distributed in the Western One Piece TCG market.
Players in Switzerland also predominantly use the international version.
OP-17 Japanese
Japanese displays are particularly interesting for collectors who prefer Japanese Trading Cards or collect different versions of a set.
However, the pack and product structure differs from the English version. Therefore, prices should not simply be compared 1:1.
Is One Piece OP-17 worth it as a Sealed Product?
From a collector's perspective, OP-17 has some characteristics that make the set particularly interesting.
These include the 4th-Anniversary theme, well-known One Piece characters, several high-class Chase Cards, and the focus on big names like Luffy, Shanks, Kaido, and Whitebeard.
However, for factory-sealed Trading Card products:
A future increase in value can never be guaranteed.
The long-term value of a sealed display depends on factors such as demand, print run, available reprints, condition, and popularity of the set.
Therefore, collectors of Trading Cards should not only focus on potential price increases but choose sets that they would also like to own in the long term.
Especially for an anniversary set like OP-17, it will be exciting to observe how demand develops after the release.
