I was under the impression they were looking to conserve copper prewar. Normal weight 3.1grams.

If your going to weigh coins, use a scale that goes to at least two decimal places and how do we know how accurate your scale is. That coin could weigh as little as 3.35 and still register as 3.4. The actual weight of a copper coin is 3.11g with a tolerance of .12g.

Also they did preserve copper in WWII when they went to the zinc plated steel cents in 1943.
