What is the rarest K-Pop photocard you have?

recently traded w someone and I got this Seonghwa bread PC (The Worl EP OUTLAW) which is rare or from the rare ATEEZ bread PC set

also traded for the Yeosang Golden Hour Pt.2 Target exclusive PC which is also rare (??) or so i've heard

(literally checked eBay for them and some of the other ATEEZ target PC ghpt2 are like 100 each)

I would just say OT9 of Stray Kids before Woojin had left

Yeah some people told me it would be crazy to have all members from the albums, before he droped out but ... they added like 5 photocards per album so it was quit easy to have one of each or multiple of some
