CEL21 · Celebrations + 25th Promos Index

On Nov 12, 2026 the Celebrations (set + 25th-anniversary promos) index (CEL21) stood at 87.95 (Oct 2021 = 100), and one raw copy of each of the 75 cards it prices cost about $844 at eBay sold prices read on PriceCharting. It is re-marked every Monday and Thursday. 100 = Oct 2021, the set's release month; months before 09/28/26 are reconstructed from monthly price history, live marks since 09/28/26. This block tracks the set; it does not recommend cards.

Method. One set, one index. The universe is every card in the set; the basket is the cards that trade as ungraded singles — at least 6 clean single-card sold comps in the trailing 30 days to enter, 4 to stay. The holo rule: 41 holo-tier cards (holos, Shinings, Crystals, secret and illustration rares — by printed rarity) are standing constituents. They are never screened out, because a set's value sits in its holos and raw holos trade slower than commons precisely because they cost more; 4 of them currently sell fewer than 4 times in 30 days and are marked on the nearest window with clean sales (90, 180 or 365 days), flagged thin and dated in the table. Price-weighted on PriceCharting's dated ungraded sold list (eBay sales, with TCGplayer sales where PriceCharting records them), never asks. The TCGplayer shop price shown beside each card is a separate number and is not in the level. No caps. The index is the cost of one copy of every card in the basket ($844 today), indexed to 100 at the base month: a card's weight is its price over that sum and moves with prices, nothing is ever trimmed, and there is no rebalance — the top card is 16.5% because that is what the set is. (The 25% single-card and 5/50 group caps used Sep 15 – Oct 12, 2026 were retired on Oct 12: a set cannot trim a Charizard the way an ETF trims a position.) Level = Σ(sold mark) ÷ divisor 9.593159; entries and exits are logged divisor adjustments; reconstitution quarterly (first Monday of Jan/Apr/Jul/Oct, announced the Monday before). The plain read's whole-set figure is the plain sum of every priced card's sold mark, one copy each, raw and uncapped, with its window and date printed; its change compares the same cards at two market marks at least five days apart and never across a divisor row. It is what the set costs to buy, not a level. 17 of 92 cards are in the universe but not the basket (non-holo cards below the screen). n30 is a liquidity gate, never a volume figure (the source caps its table at 60 rows). The 25th-anniversary set (2021) is 50 cards: 25 main cards and 25 Classic Collection reprints (which keep their original numbers, so Charizard is #4). This index also holds the 42 Celebrations-era promos PriceCharting files with the set — 17 SWSH Black Star promos and 25 oversized jumbo cards from the Celebrations collections. They are not set cards, but they came in the Celebrations products and collectors file them with the set; 25 of them trade often enough to be in the basket, and they are 35% of basket value. Reverse holo, Prize Pack and stamped prints are separate items and are not in this index. Bid buttons are live eBay auctions on the exact card (verified title, soonest close with bids first, refreshed every 15 minutes) — bids, not marks. An index is a measurement, not a call. How prices work · every ticker.
