tcdb sid 174334 renders the heading "2017-18 Panini National Treasures - Clutch Factor" and "Total Cards: 48" at https://www.tcdb.com/Checklist.cfm/sid/174334/2017-18-Panini-National-Treasures-Clutch-Factor ; 48 of 48 rows rendered in that fetch. Serial numbering is UNIFORM across the fully enumerated set: "SN99" on all 48 rows, plus "EXCH" on 2 rows, i.e. #/99. That figure is a property of the set and is written here in words only, never in card_count (EXTRACTION_SPEC 2.2). checklistcenter independently lists this set at 48 cards (https://www.checklistcenter.com/2017-18-national-treasures/) -- agreeing with tcdb. Two of the 48 rows additionally carry the "EXCH" token -- exchange/redemption cards. Recorded rather than dropped: an EXCH row converts an unresolved placeholder into evidenced absence (EXTRACTION_SPEC 3.2).
