Well actually the card itself has no value and it can't be sold on the market. It is given to you once you have (and hold liquid) 1 Million Starbits on the Hive Engine. What the card does is allow you to earn 10,000 Starbits per day, which is about 1.5 HIVE at the current price, not too bad.
Every 10 days I will be able to buy 12 card packs, that will help me advance in the game and earn even more Starbits. It is a pretty good game you should give it a try.
