Memorabilia insert - every one of its 20 rows carries the literal token "MEM" and NONE carries "AU", so it is an insert and not an auto: EXTRACTION_SPEC section 2.2 has no relic value and an unsigned swatch set is an insert. tcdb sid 168687 (https://www.tcdb.com/ViewSet.cfm/sid/168687/2017-18-Panini-Contenders) states "Total Cards: 20" and renders 20. cardboardconnection and sportscardchecklist both say 20 (https://www.cardboardconnection.com/2017-18-panini-contenders-basketball-nba-cards ; https://www.sportscardchecklist.com/sport-basketball/year-2017-18/index-panini-contenders/trading-card-checklists-and-product-information).

This set has a recorded count of 20, but the card-by-card checklist is not yet in the catalogue. That's an open research question, not a statement that no checklist exists. If you know a source that documents it, tell us — a pointer to one is exactly what closes these.
