so I was going through $200 in CWR half dollars. to no surprise, no silver. there is this one coin. I have SUPER hearing. as I was dropping the halves back in the wrapper, the last coin made a sound that was unlike any other I have heard. I got up and grabbed my scale and wouldn't you know...the kids ear was on point. I weighed another half first to see what I was working with and it came un 11.2....but the coin in question came up as 10.8. a .4 point difference. so I would like to know what the acceptable tolerance is so I know if it is within its allotted range, or may be an error? thanks in advance.
10.9 to 11.8 grams, less if well-worn. The average weight for clad halves should be 11.35 grams, so if your scale is weighing low by .1-.2g, 10.8 is still within tolerance. It could still be an oddity, but not necessarily.
I just weighed 3 different nickels and they all weighed 5.1, it looks like the scale is being generous. all the high points are pretty well defined ( ear and hair is what I am looking at.) I would take a pic but card reader isn't working with this new lap top. I know that makes it hard. if it were a thin planchet or something and WAS out of the tolerance range by .1 or .2...is it worth over thinking?
11.34 grams +/- 0.454 grams. It seems your scale is a 0.1 gram type, which with rounding would not be accurate enough to determine.
if you mean it only shows the tenths place (if memory serves correctly I think that is the term) then yes.
This site gives you weights and tolerances of all the years. You will need a scale that goes to 0.01 http://coins.about.com/od/Kennedy-Half-Dollars/ Good luck.
