Notes

tcdb sid 176611, heading read back verbatim as "2017-18 Panini Threads - Box Topper Memorabilia Prime", "Total Cards: 25" (https://www.tcdb.com/ViewSet.cfm/sid/176611/2017-18-Panini-Threads-Box-Topper-Memorabilia-Prime). All 25 rows were enumerated, never sampled: every row carries the tokens "MEM, SN1" and the distinct serial-token set over the tier is exactly {SN1}. Its 25 card codes (BTM-AWG ... BTM-ZLV) are byte-identical to the Box Topper Memorabilia set, which is why it is recorded here as a parallel rather than as a second sets.csv row, even though tcdb files it under the "Insert Sets" heading of https://www.tcdb.com/Inserts.cfm/sid/176608/2017-18-Panini-Threads ; gap opened. Corroborated by cardboardconnection's parallel list entry "Prime 1/1" (https://www.cardboardconnection.com/2017-18-panini-threads-basketball-nba-cards) and by sportscardchecklist "2017-18 Panini Threads Box Topper Memorabilia Prime (25 Cards)" (https://www.sportscardchecklist.com/sport-basketball/year-2017-18/index-panini-threads/trading-card-checklists-and-product-information). CHANNEL: two INDEPENDENT exclusivity statements cover the whole product, so CAV-010 exclusivity is earned on every row here. cardboardconnection: "Scaling back, 2017-18 Panini Threads Basketball offers one jumbo box topper memorabilia card per box in a retail-exclusive format." (https://www.cardboardconnection.com/2017-18-panini-threads-basketball-nba-cards). Panini America, first-party and off that lineage: "Panini America's retail-only 2017-18 Threads Basketball is starting to arrive on store shelves right about now (primarily Target locations nationwide)" (https://blog.paniniamerica.net/panini-americas-2017-18-threads-basketball-delivers-games-biggest-memorabilia-cards/). No channel_sku is written: the two retailers that stock the single box configuration title it differently ("5x7 Jumbo Jersey Blaster Box" at dacardworld, "5x7 Jumbo Jersey Box" at steelcitycollectibles), and a box SKU resting on one retailer's product title is not sourced. Gap opened.
