2021-22 Select

• G-001 rookie_flag is UNKNOWN for 55 cards (#82-100, #179-200, #287-300). tcdb.com is the only source found that carries explicit RC designations, and its checklist pages truncate at roughly 80-87 rows per page, so RC status could only be read for #1-81, #101-178 and #201-286. cardboardconnection, checklistcenter and gogts carry no RC markings at all.
• G-002 cardboardconnection's checklist contains no literal RC markings (confirmed by a verbatim quote pass), yet summarizing fetches of that page returned invented RC flags for players who were not 2021-22 rookies (e.g. #108 Darius Bazley, #119 Onyeka Okongwu, #139 Payton Pritchard, #149 Precious Achiuwa, #170 Isaiah Stewart, #177 Moses Brown, #274 James Wiseman). All rookie_flag values in this file come from tcdb.com only; cardboardconnection RC output was discarded.
• G-003 Card #142 Jared Butler (Utah Jazz): tcdb.com shows no RC designation although he was a 2021-22 rookie; a cardboardconnection summarizing pass showed RC. Recorded as 'no' per tcdb.com, the only explicit-RC source. Needs confirmation against the physical card.
• G-004 Card #179 is single-source: cardboardconnection shows Rudy Gobert (Utah Jazz); checklistcenter's pass showed Donovan Mitchell at #179, duplicating #178. tcdb.com page 2 truncated at #178 and could not arbitrate. Recorded as Rudy Gobert per cardboardconnection.
• G-005 Channel is UNKNOWN for 47 of 53 base parallels. No source documents hobby/retail/blaster/mega/hanger exclusivity for this release; cardboardconnection only states that Hobby H2 boxes carry exclusive Disco, Gold Disco #/10 and Black Disco 1/1, and that a 1st Off The Line (FOTL) online box exists. Red Disco #/49, Blue Disco #/25 and Green Disco #/5 are likely H2-exclusive too but this is not stated by any source, so they are left UNKNOWN.

• G-006 Tier-applicability disagreement. cardboardconnection omits Scope and Tri-Color from the Courtside parallel list and gives Premier Level a distinct 'Tie-Dye Die-Cut #/25'; checklistcenter lists Scope, Tri-Color and a single 'Tie-Dye #/25' as shared by all three tiers. cardboardconnection's per-tier lists were used.
• G-007 Print-run disagreement for Purple Die-Cut (Premier Level): cardboardconnection states #/99, checklistcenter states #/999. Recorded as 99 (cardboardconnection), since /999 falls outside the surrounding tier sequence (/249, /175, /65).
• G-008 'Pink (Marketing)' carries a different print run in each tier (#/10 Concourse, #/4 Premier Level, 1/1 Courtside). Because parallel_name must be unique, it was split into three rows named Pink Marketing Concourse / Premier Level / Courtside. Distribution channel for this promo parallel is undocumented, as is that of Lucky Envelopes #/8.

• G-009 'Rookie Private Signings Icon Version' (1 card) is single-source (checklistcenter only); cardboardconnection does not list it.
• G-010 Set-name disagreement: cardboardconnection calls it 'X-Factor Memorabilia Signatures', checklistcenter renders it 'X-Fractor Memorabilia Signatures'. cardboardconnection's name was used. Other naming variants (Auto Memorabilia / Autographed Memorabilia, Signature Set / Signatures, Rookie Jersey Auto / Rookie Jersey Autographs, Draft Selections / Draft Selections Memorabilia) are recorded in the sets.csv notes.
• G-011 beckett.com/news returned HTTP 403. Direct HTML fetch (curl) of cardboardconnection, checklistinsider and tcdb was refused by the network proxy (403 on CONNECT), so all data was read via summarizing fetches, which carries transcription risk. breakninja.com has no 2021-22 Select per-set pages and gogts.net keeps its checklist in downloadable PDF/XLSX files that could not be read.
• G-012 Insert/autograph/memorabilia card counts agree across cardboardconnection and checklistcenter but were not verified against a third source, and card-level checklists for these sets are out of scope. No base photo-variation subset was documented for this release; absence is unconfirmed.
• G-013 "75 Years of the NBA": no sourced own-parallel-tier colour list found for this non-base set. tcdb Inserts.cfm lists no colour-suffixed variant of this set.
• G-014 "Artistic Selections": no sourced own-parallel-tier colour list found for this non-base set. tcdb Inserts.cfm lists no colour-suffixed variant of this set.
• G-015 Base tier print_run, serial_numbered and channel are all UNKNOWN. Four sources fetched (cardboardconnection.com, tcdb.com set page, checklistcenter.com, cardsmithsbreaks.com) agree on the tier names and the 1-100/101-200/201-300 ranges, but NONE makes any positive statement that the base cards are unnumbered or serial numbered, and none designates any base tier as hobby-exclusive or retail-exclusive. release.csv already carries base_print_run=unnumbered with basis 'assumed'; that assumption was deliberately NOT propagated into base_card_tiers.csv. beckett.com/news/2021-22-panini-select-basketball-cards/ returned HTTP 403 again and could not be used as a fifth check. [REVIEWED 2026-08-19: still open; 112 of 145 parallels lack a sourced channel.]
• G-016 DISCREPANCY between our prose and the sources on 'die-cut'. sets.csv Base Set notes and release.csv notes both say Premier Level #101-200 is '(die-cut)'. No source consulted says the base Premier Level card itself is die-cut: cardboardconnection.com uses 'Die-Cut' only inside PARALLEL names (verbatim: 'Blue Die-Cut #/249, Maroon Die-Cut #/175, Purple Die-Cut #/99, Orange Die-Cut #/65'), and instead characterises the tiers differently, verbatim: 'The short-printed base tiers include Premier Level and Courtside.' checklistcenter.com likewise attaches die-cut to Premier Level's parallels, not to its base cards. The sourced reading is that die-cut is a parallel treatment (and that Premier Level and Courtside are short-printed relative to Concourse); the prose claim that the base Premier Level card is die-cut is unsourced. sets.csv and release.csv were left untouched per the repair spec.
• G-017 SOURCE-OF-RECORD NOTE for six insert_cards rows. Six cards named on the cardboardconnection checklist for their set do not appear in tcdb's BASE subset for that set, because the card was issued ONLY in parallel form; their printed codes were therefore read off tcdb's Black Prizms (1/1) subset, which carries the complete run. cardboardconnection states the exclusions verbatim: 'Dirk Nowitzki only in Black; Magic Johnson, Oscar Robertson not in Green Ice' (Selection Committee Signatures); 'Buddy Hield not in Base/Purple' (Autographed Memorabilia); 'Usman Garuba, Josh Christopher not in base' (Draft Selections Memorabilia); 'Josh Christopher, Usman Garuba not in Base/Red Wave/Purple/Tie-Dye/Neon Orange Pulsar/Gold/Gold Wave; Isaiah Livers not in Base/Red Wave/Purple/Tie-Dye' (Rookie Jersey Autographs). Affected rows: Selection Committee Signatures SC-DNK Dirk Nowitzki; Autographed Memorabilia AM-BHD Buddy Hield; Draft Selections Memorabilia DS-UGR Usman Garuba and DS-JCH Josh Christopher; Rookie Jersey Autographs RJ-JCH Josh Christopher, RJ-UGR Usman Garuba, RJ-ILV Isaiah Livers. Signature Selections SS-RHM (Rui Hachimura) and Signatures SG-KHM / SG-TYG were also absent from tcdb's base subset and taken from the Black Prizms subset, but for those three cardboardconnection gives no exclusion note, so whether they are genuinely parallel-only or simply a tcdb omission is UNRESOLVED. All nine are counted inside sets.csv card_count, so row counts match exactly.
• G-018 DUPLICATE PRINTED CODES within a single set - written verbatim, not de-duplicated. (a) Rookie Signatures RS-KJN appears on two cards, Kai Jones and Keon Johnson; CONFIRMED by two independent eBay listing titles: https://www.ebay.com/itm/285726653636 '2021-22 Select KAI JONES #RS-KJN Rookie Auto Neon Green Prizm /99 Hornets' and https://www.ebay.com/p/15057550357 '2021-22 Panini Select - Rookie Signatures Keon Johnson #RS-KJN Silver Prizm /249'. (b) Draft Selections Memorabilia DS-KJN likewise appears on Kai Jones and Keon Johnson (tcdb base subset sid/335421 and Black Prizms subset sid/335422 agree); no marketplace listing was found for either, so the collision is PLAUSIBLE-BY-ANALOGY but not independently confirmed. Note Rookie Jersey Autographs does NOT collide - it uses RJ-KJN for Keon Johnson and RJ-KJS for Kai Jones. (c) Signatures SG-RHM appears on Rui Hachimura and Richard Hamilton (tcdb sid/335506 and sid/335507 agree; cardboardconnection lists both players in the set). Rui Hachimura's SG-RHM is confirmed by https://ebay.com/p/20057544669; Richard Hamilton's is NOT - the only SG-RHM Richard Hamilton listing found (https://www.ebay.com/itm/236902919421) is a 2021-22 Panini PRIZM card, and Prizm's Signatures set uses the same SG- prefix, so tcdb may have carried the code across products. Richard Hamilton's Select code is therefore UNCERTAIN.
• G-019 card_number is NOT unique across this release, by design and by source. (i) Two different sets both use the SS- prefix: Selective Swatches (memorabilia) and Signature Selections (autographs). They collide on exactly one code, SS-MCL, which is Mike Conley in BOTH sets. Resolvers must key on (set_name, card_number), never card_number alone. (ii) 75 Years of the NBA occupies printed numbers 51-75, which also overlap nothing in this product's base run (base is 1-300) but DO overlap the same-named insert in sibling 2021-22 products - see G-021.
• G-020 Two printed codes for Dominique Wilkins look anomalous and could not be corroborated outside tcdb: Signature Selections 'SS-MWL' and Selection Committee Signatures 'SC-SWL'. Both were written verbatim as tcdb prints them, and both are confirmed by TWO tcdb views (the set's own checklist and its Black Prizms subset), but no marketplace listing quoting either code was found. Neither code follows the initials pattern the other codes in those sets use (compare In Flight Signatures 'IF-DWL' for the same player, which IS corroborated by https://goldin.co/item/2021-panini-select-in-flight-signatures-ifdwl-dominique-wil2fypo). Per spec, codes are never derived from initials, so no correction was invented; the rows stand as sourced and are flagged here.
• G-021 NUMBERING-SCHEME FINDING, recorded because it contradicts the natural reading of sets.csv. '75 Years of the NBA' has card_count 25 but its cards are printed #51-75, not #1-25 - Select's slice of a 75-card run shared across Panini's 2021-22 products (2021-22 Prizm's 'Optic Update 75 Years of the NBA' rows already in this repo run #26-50). Confirmed by three independent sources printing 51-75: tcdb https://www.tcdb.com/Checklist.cfm/sid/335414/2021-22-Panini-Select-75-Years-of-the-NBA, cardboardconnection https://www.cardboardconnection.com/2021-22-panini-select-basketball-nba-cards, and COMC https://www.comc.com/Cards/Basketball/2021-22/Panini_Select_-_75_Years_of_the_NBA/62/Dirk_Nowitzki/21463752 ('#62 - Dirk Nowitzki'). Note this is the ONE set in this release where cardboardconnection did not renumber; on every coded set it did (verified: it renumbers Signatures 1-30 where the printed codes are SG-xxx), so it was used for membership only.
