    1983 Brass penny

    recently I received a roll of pennies from our local bank. In one roll were 5 pennies that appear to be brass, they are all 1983 D and have a color like brass and stand out, you are able to pick them our of a pile of pennies face down. Was this a special minting or something?

    In my opinion, I think it I'd a good idea to eeigh them, but it's important to be accurate so a scale that can go down to one hundredth of a gram is good (x.xx g). A scale that only has one decimal point may round up or down weight, and for this purpose may give a false reading. Scales can be bought on Amazon for less than 20 bucks or so, shipped.

    The weight for copper is 3.11 grams, give or take within a legal tolerance.
    Zinc style Lincolns weigh close to 2.5 grams.

    A coin in a roll can tone, if one tones in a roll several coins near it may tone as well. Toning can occur from paper rolls, temperature change and how the coins were handled and other reasons.

    If you don't have access to a scale, some times you can drop a copper cent onto a hard flat surface like tile or marble and get the coin to give you a ring type sound, Zinc cents typically only offer a dull thud.
