I picked up this parallel from the 2018 Panini National Treasures Collegiate set. This is the Century Gold card, which is serial numbered to 10, this one being #6. Also in the Hoard, along with the base card, is the Century Emerald version(#'d to 5) and a Printing Plate(one of one).
I am still lacking the Century Silver(#'d to 49) , the Century Red(#'d to 25) and the Century Black(one of one). Bear in mind this is only the parallel versions for Walker's card #33. There is also a card #13 of Herschel in this set. The front has a different pose, but the available parallels are the same.
