Thank you, that's where my 2.9 grams is coming from, I didnt know there was a bronze alloy. I wish you luck on your endeavor. Merry hunting sir.
When I CRH cents, I weigh all 1982/83 cents, and no...it does not take very long. Two hands + two scales = twice as fast. Even going through a box, I won't end up with many more than one or two hundred that are 1982/83. That's less than five minutes per box to weigh. Now, weighing all cents post-1982...I'm sure that would take much much longer to do. But, so is checking for all ODV/RDV, DDO/DDR, RPM, MM styles, etc...
