2006 Five Cent Filled 6" A Small Study

Here is a small tidbit of info, for those "die chip", collectors, after dozens of boxes searching , I have managed to gather a roll of 2006 five cent filled six`s! There seems to be maybe three varieties, side filled, top filled, and completely filled six. The point here, is out of all those that I have found, there is a higher ratio, of no mark,to "P"`s, but, out of all that searching, I actually have only found"one", with a mint mark!
