151: How to Identify Cards From This Set

• This set focuses exclusively on the original 151 Generation I Pokémon, reimagined with modern card mechanics and Kanto-themed illustration rares.
• The set totals 210 cards in the English release (165-card main set plus SR/SAR/UR secret rares numbered up to 210).
• An independent card database confirms card No. 1 of this set carries Regulation Mark G, matching the era of Scarlet & Violet and Paldean Fates.

• [Base Set](/lookup/pokemon-sets/base-set): The vintage, unofficial 'Original 151' checklist that some collectors reference is not a real Pokémon TCG expansion — it is assembled from cards spread across three separate 1999 sets — unlike the single official 2023 '151' expansion (abbreviation MEW), which predates the regulation-mark-free vintage era by more than two decades.

Bulbapedia's infobox field lists 'encards=207', which is inconsistent with the article's own prose ('a special expansion containing 210 cards') and with the highest numbered card actually present in its card list (210/165); the 210-card figure is used here since it is corroborated by both the prose and the full card list. Japanese name is 'Pokémon Card 151'.

• Bottom-left or bottom-right corner: the set symbol and the collector number (e.g. 4/102) tell you the set; older cards have no symbol at all, which itself narrows them to Base Set.
• Left of the number: a 1st Edition stamp, if present, sits below the art on WOTC-era cards.
• Regulation mark (a letter in a box near the bottom, D through H so far) dates modern cards to a two-year window.
• Back of the card: the blue Poké Ball back has changed little since 1999; a washed-out, blurry or wrongly colored back is the first sign of a fake.

Lay the card flat on a dark surface in daylight, straight on, with the whole card in frame, then a close-up of the bottom edge where the set symbol, number and any edition stamp sit. Tilt holo cards under the light for a second shot to show the foil pattern. Photograph the back too. The app reads the card and set; the edition and rarity checks above tell you which version you have.
