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.
| Listing type | Ended | Sold | Sell-through |

| loose packs | 186 | 117 | 62.9% |
Auctions only — buy-it-now listings are counted separately and are not in this table. Sell-through uses auctions whose outcome eBay reported; unsold auctions stay in the denominator.

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.
