Nine cards in this exclusive set from Panini Court Kings. You never see these up for sale. Each card numbered is a one of one and represents his last name. This one is the "S" the ninth letter in porzingiS' last name. They only do this for one or two star rookies every year. Other nameplate patches have parts of a jersey or letter but not the whole letter and its print run is 25 or more. This RC of Porzingis will only have 1 card assigned to the "S" not 9 so is truly a 1/1.
I also have his seventh letter "G" which is the 7/9 of this set also for sale, also a 1/1 as I mentioned.
Truly a must-have for any high-end Porzingis collector.
