Why this is the earliest card
No source consulted shows an RC logo or an RC flag on any Holly Holm card, and SportsCardsPro's card detail field reads 'Is Rookie Card: No' for both of her 2015 base cards. So this is recorded as her earliest significant card rather than a designated rookie. 2015 Topps UFC Knockout #100 is the pick: Cardboard Connection dates the product to 22 April 2015, roughly eight weeks after her UFC 184 debut, and no earlier licensed Holm card of any kind — boxing, MMA or multi-sport — could be found. Cardboard Connection's 2014 Topps UFC Bloodlines checklist (17 December 2014) does not contain her, which closes off the most likely pre-2015 possibility.
The first Holly Holm trading card of any kind that could be documented, from a product Cardboard Connection dates to 22 April 2015 — about eight weeks after her UFC 184 debut and seven months before she knocked out Ronda Rousey. She occupies #100, the final slot in the 100-card base checklist, which is where late checklist additions usually land. Its Mat 1/1 parallel is the single most chased piece of Holm cardboard; Collectibles.com's page for her headlines the '2015 Topps UFC Knockout Mat #100'.
Collectibles.com's Holly Holm register states 'Holly Holm debuted as a Rookie in 2015' but does not name a card; SportsCardsPro marks her 2015 base cards 'Is Rookie Card: No'. Cardboard Connection has no Holly Holm player guide (its /player/holly-holm URL returns 404), so the usual tiebreaker is missing. The release-order argument for Knockout #100 rests on Cardboard Connection's dates alone.
Sellers describe the 2015 Topps UFC Knockout #100 Silver /199 and Gold /99 as 'the rookie'; they are parallels of the same card. Collectibles.com's automated 'Top Rookie Cards' block for Holm lists 2025 Topps Midnight UFC Glimmer Graphs autographs, which are not rookie cards by any reading.
Identifying it
- Card number 100 — the last card of the 100-card base set.
- Base parallels for the product run Silver /199, Gold /99, Red /8 and Mat 1/1; a card without a stamped serial is the unnumbered base.
- The FightCardboard set record for 2015 Topps UFC Knockout independently gives the same 22 April 2015 release and the same parallel ladder.
