All mammals with an estimated population of less than 100,000 have a Holographic card. The print run number follows the animal.

* The South China Tiger is a card that does not link directly to the animal's estimated population. It is thought to be extinct in the wild. 8 is a lucky number in China so we thought it was only fitting, maybe there's still a few out there. Over 100 are currently in sanctuary's.

* There are only an estimated 4,000 Wild Water Buffalo, however there are 200 million domestic.
* There are only an estimated 30,000 truly wild American Bison, the rest are in privately owned herds.
* There are 2 Million domestic Bactrian Camels.
* There is not enough research to give accurate population estimates for the European Pine Marten, Ground Pangolin, Honey Badger, Black Squirrel, Aye Aye, Kit Fox and the Margay.

Cards 0-53 also have non-holographic versions, not directly linked to population.
