Halves on average have 10 coins per ender, but of course there are more coins in a penny roll and therefore an ender represents a larger piece of the total haul. Because penny rolls have 50 coins per roll, statistically you should get 25 wheats for each ender. at 7 enders on one side, 14 total enders would mean you may have 350 wheats in there! badabing badaboom get that baby opened and make sure to be on the lookout for errors! (think about it, that's a dumped collection, and what do cent collections have besides wheats)
