25c range of use

Here is a first attempt at establishing range of use as well as relative rarity of each printing. With the exception of one of the 1E4s (highlighted in red), all of the dates are within range-i.e. there aren't any early uses one or two years before the known earliest use from looking at many specimens over the years.

The 25c1E1 is very rare, 50 percent of this sample are 1E3c's-the symmetrical box grid, and most of the other papers are also rare. The results from this small sample are consistent with my previous experience.
