As a newbie hand sorter I have now accumulated over 800 1982 pennies and I will be receiving a Triton T2 300 digital scale from ebay any day now so I can determine which of the 800 are copper or zinc. I wanted to ask experienced weighers of '82's if there is a "gray" area in which I will have to make a guess as to whether a particular coin is copper or zinc. In other words will all zincs weigh in at 2.5 grams or less or will some zincs weigh it at 2.6, 2.7 or even 2.8? Similarly will some coppers, with average wear, weigh less than 3.1 such as 2.9, 2.8 or 2.7?
My concern is that some coppers might weigh in low near 2.8 grams and similarly some zincs might come in heavy near the 2.8 mark and cause a "gray" area requiring me to make a guess. Just trying to anticipate any problems as I don't want to unknowingly throw in any zinc '82's into my copper pile. Any advice from experienced '82 weighers is greatly appreciated, Don.
