With regards to the cards, in each pack you get five different ones. You get one star card, two planet cards and two moon cards (these are just the classification symbols).
I believe the stars run from number 1-20, planets from 21-40 and moons from 41-60.
Numbers 61-70 are INCREDIBLY rare and often fetch over $90 on eBay.
(this last bit's off the top of my head, so forgive any mistakes but I'm sure about the 61-70 cards being rare)
