Panini continues to astound me with the mish mosh way they issue their cards. Cards with numbers not matching the checklists, different dates from the date of issue, etc. This is a base card of Herschel from the 2018 Panini National Treasures set, an "update", I guess, but the card is dated 2015, and is from the multi sport collection. Why not just date it 2018, and call it an update on the card itself?
I uploaded this card to Herschel's 2015 page on the TCDB, as there was a space already there with the correct card #, and serial #. Speaking of serial numbers, this card is #70 of 99.
You may ask, if I'm so confused by Panini, why do I collect them? The answer is, as a single player collector, you try to get as many different cards as you can. You know you'll never get them all, but if you come across one you don't have, it becomes a target.
