I decided to post these two cards together. They are similar in that they are both from the 2018 Panini National Treasures Collegiate set, and they are both serial numbered to 99.
The difference is in Herschel's pose on each card, and the trim difference. Here is the #13 card, front and back:
This particular card is #12 of 99. Next, here is the #33 example:
This one is serial numbered 61 out of 99. These cards also have parallel versions. Gold, Emerald, etc, with lesser print runs.
