Celebrations: How to Identify Cards From This Set

• Every main-set Celebrations card (numbered only 1-25) carries the gold Pokémon 25th Anniversary logo, distinguishing it from ordinary Sword & Shield-era cards.
• The main set is unusually short (only 25 cards) because it commemorates the TCG's 25th anniversary rather than being a full expansion.
• An independent card database lists card No. 1 of the main Celebrations set as Regulation Mark E.

• Classic Collection (reprint subset): Classic Collection cards keep the card number, rarity, and copyright line of their original historical printing (rather than being numbered 1-25) and have an added etched Confetti Holofoil finish plus the 25th Anniversary logo.

• Celebrations: Classic Collection: Classic Collection cards are reprints of older cards (e.g. a Charizard bearing its original 1999 Base Set number) with a shiny Confetti Holofoil texture; they are not legal for tournament play, unlike main-set Celebrations cards.

Bulbapedia's set infobox records 50 total English cards for 'Celebrations', which appears to combine the 25-card main set and the 25-card Classic Collection subset packaged with it; the Japanese '25th Anniversary Collection' counterpart is a differently-structured 30-card set with its own Reverse Holo parallel print run.

• 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.
