    The coloring is probably chemical residue.
    It's called toning. It could be natural, environmental damage, heat.. etc.

    Silver dimes weighed 2.5 grams and the modern clad dimes weigh 2.27 grams.
    Several possibilities:
    1. It's slightly heavy.
    2. The scale is slightly off.
    3. Oxygen has weight and the oxidized metal has added .13 of a gram.

    Thanks but the weight still has me confused! This is supposed to weigh 2.27 . This one is 2.4 ? I know nothing about these coins!

    Thanks @Michael K was posting my last message when yours came up. I didn't realize that oxidize metal could add almost 1 and 3/4 grams to a coin. And my first thought was this was a typical toning of older silver coins.

    I think you need to check your math. ;)

    Weigh a few other clad dimes from your pocket change, and tell us what your scale says about those...?

    Clad dime is supposed to weigh 2.268 grams +/- .091 grams So maximum weight to be in spec is 2.359 grams. If your scale is only good to one decimal place that will round off to 2.4 grams

    There is a +/- tolerance level.
    A dime that weighs only .07 (7 hundredths of a gram) more is still inside
    the acceptable range. And again, that is if your scale is precise. It could be off slightly.

    Glad I could help, even if the help was for someone else over a year ago. :)
