Coins are evenly distributed at 2 per Bonus/Value box. Retailer exclusive cel cards have the same odds as the common white bordered ones. However, because there are only 5 of each for Wal-Mart and Target, that should make them easier to get (if you're buying from the Gravity Feeds that is).
I will do my best to include this on the Topps site. If not, I will be happy to answer any additional questions here.
