hist1 = Histogram[RandomReal[
   NormalDistribution[0, 1], 200]]

Cases[hist1, 
 RectangleBox[{x1_, 0}, {x2_, y_}] ->
  {(x1 + x2)/2, y}, Infinity]

For multiple histograms you will have to split the data. For example,

data1 = RandomReal[NormalDistribution[0, 1], 500];
data2 = RandomReal[NormalDistribution[3, 1/2], 500];

hist2 = Histogram[{data1, data2}]

Split[Cases[hist2, RectangleBox[{x1_, 0}, {x2_, y_}] ->
   {(x1 + x2)/2, y}, 
  Infinity], First[#1] < First[#2] &]

How can I access the {x,y} values that are plotted by Histogram?
