One possibility: I have a set of those coin tubes where they have a slot that you can dump out the excess coins and roll the prescribed quantity. I noticed recently that the tubes are grossly inaccurate (at least for pennies).
County fair was in town, so I decided to roll up some zinc for extra fair money. My bank has a location open on Sunday in a Wal-Mart, so I figured I use it as a "dump bank." It was a good thing I counted before I rolled the tubes, because the tube would've shorted me 2-3 cents per roll. Figure the tube was made to accommodate both copper and zinc, but with copper out of the equation.....
Could it be possible that there is a measurement difference between the 90%, 40%, and Clad Halves edge wise?
