Each code has a value of $2-$8 these are not those junk pack codes you find all over, they need to be won in tournaments. As for what you get the odds are 50/50, I had one person get a secret rare mega charizard ex, another get tapu lele both $50 cards even in virtual they can be sold at that. But you have the few that get a bad ex or junk, It is all up to luck. Starting bid is 200k place and bid only near 2 days left you could win.
