Hello gents,
I've seen some posts before on the idea of weighing boxes of coins to determine how much copper is in them. I currently don't own an accurate scale, so I can't perform this test myself....but does anyone know the combined weight of a box of zincs, complete with wrappers etc? By my estimation, if you know this weight, you can determine pretty much down to the cent how much copper is in a given box by taking the weight difference between the box with copper in it, subtracting the weight of a box full of wrapped zinc, and dividing the remainder by (<average copper cent weight> - <average zinc cent weight>).
Has anyone tried this?
