How OP-15 cards actually sell at auction

Over the 30 days to 2026-09-29 we settled 2,362 ended eBay auctions carrying OP-15 cards — every one read again after it closed, so these are results, not asking prices. 27.9% found a buyer and 72.1% passed unsold, for $47,714 in hammer value. The median winning bid was $11.5 with 4 bidders on a typical sold lot.

Skypiea's god gets his card

Adventure on Kami's Island takes the run to Skypiea, and Enel — the villain the fandom never stopped quoting — finally gets a manga-art chase worthy of the memes. A Koby carrying its EB-04 stamp and another Hancock SP complete the top three.

This is one of the newest main sets in the tracker, which means the data window behind this page is short: fewer completed sales, thinner population counts, wider error bars. We publish what we have and blank what we cannot verify — read every figure on a set this young as a first reading, not a verdict.

OP-15 box price: the tracked trajectory

The Japanese Adventure on Kami's Island sealed box entered our tracking in Jun 2026 around $92 and stands near $95 as of 2026-09-27 — it gained 3% over the window, peaking at $109 in the week of 2026-08-23. The English-language Adventure on Kami's Island box trades near $272 as of 2026-09-29 (+23% over its tracked window) — about 2.9x the Japanese box (JP as of 2026-09-27, EN as of 2026-09-29). This ratio does not explain why.

How the OP-15 box price compares with its tracked range (Sep 2026)

The box trades at $95, 13% under its tracked peak of $109 and up 3% over our tracking window. The top card alone (Enel OP15 118 Manga) is worth about 6.7x the box, so the visible chase value is highly concentrated. Official pull rates are unpublished. It is not opening expected value.
