2018 Panini Select Zebra Prizm #66 Patrick Mahomes PSA GEM MINT 10 (Pop 1 of 3). Remarkable card featuring the Kansas City Chiefs' signal-caller is highly coveted as it combines great colors with the zebra motif. Encapsulated by PSA and graded GEM MT 10, this is only one of three in the world to receive this grade with none higher. Though there is no serial number, only one zebra card is available per case and this parallel to the main Panini set has proven to be very popular with such a limited print run.
