2019-20 Select

• G-001 No source presents explicit RC / Rookie Card designations on the 2019-20 Select base checklist; Cardboard Connection, Checklistcenter and Beckett all list players without RC notation. rookie_flag is therefore UNKNOWN for all 300 base cards even though the set clearly contains 2019 draft rookies (Zion Williamson, Ja Morant, RJ Barrett and others).
• G-002 Premier Level Orange Die-Cut print run disagreement: Cardboard Connection states #/65, Checklistcenter states #/66. parallels.csv uses 65 (Cardboard Connection, the more detailed source).
• G-003 Premier Level Neon Orange Pulsar FOTL #/13 is listed for the Premier Level tier by Checklistcenter only. Cardboard Connection lists Neon Orange Pulsar for Concourse and Courtside but not Premier Level; Beckett omits it entirely. Single-source, included with single confidence.
• G-004 Tmall Red Wave and Tmall Gold Wave print runs are not documented by any source consulted. Their existence is confirmed by two sources (Cardboard Connection and COMC/Badger Breaks listings) but the numbering is unverified; both are recorded as unnumbered, which may be wrong.
• G-005 Tmall Lucky Envelopes #/8 is single-source (Cardboard Connection only). Neither the COMC listings nor Badger Breaks confirm a Lucky Envelopes parallel for this release.
• G-006 In-Flight Signatures card count disagreement: Cardboard Connection shows 29 cards (numbered 1-30 with no card 2), Checklistcenter lists 30. sets.csv uses 29.
• G-007 X-Factor Memorabilia Signatures card count disagreement: Cardboard Connection lists 24, Checklistcenter lists 25. sets.csv uses 24.
• G-008 Beckett's Courtside parallel list omits the Neon Orange Pulsar FOTL parallel that both Cardboard Connection and Checklistcenter document, and Beckett lists no print runs at all. Beckett also shows base set size as TBA. Beckett was usable but is less complete than the other two sources.
• G-010 Insert/autograph card counts come primarily from Cardboard Connection with partial agreement from Checklistcenter; Breakninja and Beckett did not provide per-set counts. Counts for Artistic Selections (9), Phenomenon (40), Select Company (15), Select Future (30), Top Selections (15), Draft Selections Memorabilia (30), Select Swatches (20), Sparks (10) and Throwback Memorabilia (40) are effectively two-source at best and unverified beyond that.
• G-011 Rookie Jersey Autographs Disco Prizms is listed by Cardboard Connection as a distinct 40-card autograph set, but it is more plausibly a parallel of the base Rookie Jersey Autographs set. It is NOT included as a separate row in sets.csv to avoid double counting; classification unresolved.
• G-012 "Artistic Selections": no sourced own-parallel-tier colour list found for this non-base set. No colour-suffixed variant of this set found on tcdb's Inserts.cfm page for this release; existing note already flags it as a super short print with no parallel structure documented.
• G-013 base_card_tiers.csv written: Concourse 1-100, Premier Level 101-200, Courtside 201-300, 100 cards each. Ranges independently corroborated by psacard.com CardFacts (explicit ranges), checklistcenter and cardboardconnection (per-tier 100-card checklist sections); beckett names the three tiers but publishes no ranges and shows set size as TBA. No source consulted states whether the base cards are serial numbered or unnumbered, so print_run and serial_numbered are UNKNOWN in every tier row even though release.csv carries base_print_run=unnumbered with base_print_run_basis=assumed. No source consulted states that any of the three tiers is hobby-exclusive or retail-exclusive, so channel is UNKNOWN; cardboardconnection only describes hobby box composition (10 Premier Level and 2 Courtside cards per 12-pack box) and states retail exclusivity for parallels, not for tiers. [REVIEWED 2026-08-19: still open; 55 of 97 parallels lack a sourced channel.]
• G-014 Tier name variance for the middle tier: psacard.com prints "Premier" while cardboardconnection, checklistcenter and beckett print "Premier Level". base_card_tiers.csv records "Premier Level" as the majority form. No range disagreement between sources; the sets.csv base-row prose matches the sourced partition exactly.
• G-015 X-Factor Memorabilia Signatures written PARTIAL: 23 of the 24 cards in sets.csv. tcdb lists 23 XF- coded cards (https://www.tcdb.com/Checklist.cfm/sid/227346/2019-20-Panini-Select---X-Factor-Memorabilia-Signatures), and its Gallery view states 23 total. Cardboard Connection (https://www.cardboardconnection.com/2019-20-panini-select-basketball-nba-cards) and checklistcenter (https://www.checklistcenter.com/2019-20-panini-select-basketball-card-checklist/) both list 24 players -- one more than tcdb: Josh Okogie, Minnesota Timberwolves, which both sites flag with an asterisk and give as #/25 while every other card in the set is #/199. No source that prints real card codes carries an Okogie card in this set: he is absent from tcdb, absent from sportscardspro's set page (https://www.sportscardspro.com/console/basketball-cards-2019-panini-select-x-factor-memorabilia-signatures) and no eBay/COMC listing for a 2019-20 Select X-Factor Okogie could be found. His printed XF- code is therefore unsourceable and the row was omitted rather than guessed (codes in this release are not derivable from initials). Two readings are possible and neither is confirmed: (a) tcdb is missing a real card, or (b) the Okogie card was on the sell sheet but never produced. This also reconciles gap G-007: Cardboard Connection and checklistcenter list the SAME 24 players; checklistcenter's stated '25 Cards' is a miscount of its own list, which runs 1-25 with no 7 and therefore has 24 rows. sets.csv's count of 24 is supported.
• G-016 Reconciles gap G-006 (In-Flight Signatures count). tcdb lists 29 IF- coded cards for this set (https://www.tcdb.com/Checklist.cfm/sid/227288/2019-20-Panini-Select---In-Flight-Signatures). checklistcenter's header says '29 Cards' in the body but its list runs 1-30 with no card 2, i.e. 29 rows -- the same 29 players Cardboard Connection shows. All three sources agree on 29 cards and on the same player roster. sets.csv's count of 29 is confirmed. The '1-30 with no card 2' sequence recorded in the sets.csv note is Cardboard Connection's / checklistcenter's own display numbering, NOT the printed card numbers, which are IF- letter codes.
• G-017 NUMBERING SCHEMES ARE MIXED WITHIN THIS RELEASE and the aggregator sources renumber the coded ones. Verified per set against tcdb (which prints real codes) with marketplace corroboration: LETTER-CODED -- Artistic Selections (AS-), Draft Selections Memorabilia (DS-), Select Swatches (SS-), Sparks (SP-), Throwback Memorabilia (TM-), Rookie Jersey Autographs (RJA-), Rookie Signatures (RS-), Signatures (SG-), Autographed Memorabilia (AM-), In-Flight Signatures (IF-), X-Factor Memorabilia Signatures (XF-). PLAIN 1..N -- Phenomenon (1-40), Select Company (1-15), Select Future (1-30), Top Selections (1-15). No base-mirrored or own-block set was found in this release. Calibration evidence for the coded scheme: sportscardspro lists this set's Ja Morant Rookie Signatures as #RS-JMT (https://www.sportscardspro.com/game/basketball-cards-2019-panini-select-rookie-signatures/ja-morant-tie-dye-prizm-rs-jmt) and Wesley Matthews X-Factor as #XF-WMT (https://www.sportscardspro.com/console/basketball-cards-2019-panini-select-x-factor-memorabilia-signatures); an eBay listing title reads '2019-20 Panini Select - X-Factor Memorabilia Signatures Jalen Brunson #XF-JBR'. Calibration for the plain scheme: tcdb and checklistcenter give byte-identical 1..N orderings for all four plain sets, and tcdb shows no codes for them. CONTRADICTION WITH EXISTING DATA: several sets.csv notes quote Cardboard Connection / checklistcenter display numbers as if they were card numbers (e.g. the In-Flight Signatures note's '1-30 with no card 2'); those are renumberings, not printed numbers. sets.csv was not modified.
• G-018 DUPLICATE PRINTED CARD CODES are genuine in this release and are written verbatim, so card_number is not unique within these sets. Select Swatches: SS-DRS on both D'Angelo Russell (Golden State Warriors) and Derrick Rose (Detroit Pistons) -- confirmed verbatim on tcdb's Gallery.cfm view as well as its checklist view, and both players appear on the checklistcenter roster of 20. Throwback Memorabilia: TM-DMC on both DeMarcus Cousins and DeMarre Carroll, and TM-DRS on both D'Angelo Russell and Derrick Rose -- all four on the checklistcenter roster of 40. Autographed Memorabilia: AM-TCH on both Tyson Chandler and Tom Chambers -- both on the checklistcenter roster of 25. In each case the set's total still matches sets.csv, so the duplicates are additional cards rather than double-counted rows.
• G-019 Minor source disagreements not affecting card counts or numbers; tcdb's values were written. Top Selections card 13 Anthony Davis: tcdb says New Orleans Pelicans, checklistcenter says New Orleans Hornets (the card is a throwback-era design, so the Hornets reading may be the one printed). Phenomenon card 3: tcdb prints 'Kevin Knox', checklistcenter prints 'Kevin Knox II'. Artistic Selections is numbered 2-10 by checklistcenter (9 rows) while the printed identifiers are AS- codes, so checklistcenter's offset carries no meaning for our data.
