2016 was the first year of the Disc Golf Pro Tour so these cards are largely considered all of the players first cards or even some call them rookie cards even though some may have been "touring" prior to 2016, there was only the National Tour through the PDGA and there were no card sets made prior (well for 2 decades). The only person who had another card in 2016 was Paul McBeth in the Topps Allen and Ginter set.
