Set notes — price context, reprints, factory-seal check
OP-17 box price, release-week supply and factory-seal checks
As of 2026-08-30, current eBay asks center near $150 across 21 verified listings. Completed eBay sales last put the box near $160 on 2026-08-30. OP-17 released in Japan on 2026-08-22 and in English on 2026-08-28, so both series here start at release week — early points reflect launch supply, not a settled market. Single-card data is added once the chase list is verified.
Reprint record: One pre-release Premium Bandai lottery is on record (2026-07, entries before the 2026-08-22 release). That is advance allocation of the initial print run, not extra supply, and no post-release restock has been recorded yet.
Factory-seal check: For a fresh set like OP-17, insist on photos of the uncut Bandai security tape, both side seams and the product code. Release-week stock moves fast, so re-taped opened displays do circulate — added shrink alone is not factory-seal evidence.
