Letter-coded BTR-CSWa ... BTR-ZCL. Card count from tcdb's "Total Cards: 25" line at https://www.tcdb.com/ViewSet.cfm/sid/176612/2017-18-Panini-Threads-Box-Topper-Memorabilia-Rookies , heading read back verbatim as "2017-18 Panini Threads - Box Topper Memorabilia Rookies". THE HEADER AND THE ROW COUNT DISAGREE AND THE HEADER IS RIGHT: https://www.tcdb.com/Checklist.cfm/sid/176612/2017-18-Panini-Threads-Box-Topper-Memorabilia-Rookies?sort=0 renders 50 rows over 25 distinct card numbers, because an image-variation layer duplicates each number - the rows come in a/b pairs (BTR-CSWa / BTR-CSWb) or as a bare code repeated with the literal token "VAR". The 25 is therefore a count of distinct issued numbers, which is what card_count means; the variation layer is carried as an Image Variation row in parallels.csv. Confirmed from a third lineage: the 25-code roster is reproduced exactly by the Prime tier at https://www.tcdb.com/ViewSet.cfm/sid/176613/2017-18-Panini-Threads-Box-Topper-Memorabilia-Rookies-Prime (25 rows, BTR-CSW ... BTR-ZCL, no suffixes), and sportscardchecklist lists "2017-18 Panini Threads Box Topper Memorabilia Rookies (25 Cards)" (https://www.sportscardchecklist.com/sport-basketball/year-2017-18/index-panini-threads/trading-card-checklists-and-product-information). Distinct flag tokens across the whole sid: "MEM" and "VAR"; NO row carries a token beginning with "SN", on both fetches. Not signed, so filed as insert.
