Hey IconicExpert, I have an idea regarding the special edition cards. Like the color of the card can be a similar green like American Express. Have Liberty's face in the middle of the Card with a unique border (maybe a 5 pointed star pointed up not down lol). Liberty's color can be her regular dark green color or perhaps in gold. Maybe as a background effect you can have binary code in a nice small size (like when you hold the card in different angles it should seem like its holographic).

I am providing a link into what the color green symbolizes: http://www.empower-yourself-with-color-psychology.com/color-green.html

What the color gold symbolizes: http://www.empower-yourself-with-color-psychology.com/color-gold.html

Perhaps later on when the community grow a bit more for press coverage the community can chip in to donate to some causes or fund a project.
