The company seems to be called Authenticated Ink, All Rights Reserved. There is nothing on the back. I searched around a bit but didn't find much, just a discussion about these coming out in 2008 and in 2011 or something like that.

I bought them first of all cause they're pretty neat and they combine 2 of my 3 favourite things to collect :) Some of the older pennies, especially the 1899 penny in the David Crockett can be worth much more than what I actually paid for the card. I wasn't too interested in let's say a 1984 nickel depicting Wayne Gretzky. I only picked up some of the older pennies/cards.

As you can see by the David Crockett their are also cards depicting historical figures as well as all 4 major sports and more.
