For this to be worth anything, it would have to be a proof which is a very shiny, mirror like surface. This is a regular circulated dime, worth 10c.
but if the coin was in use ,and after time shiny surface just disappear ,it can happen ?it still have some shining .
To the OP, a lack of mintmark on this date means it was struck in Philadelphia who did not start putting mintmarks on coins until 1979 I believe, (maybe 1977). The "no S" that is valuable is a proof coin only struck in San Francisco that year. However, they were only sold in proof sets at a premium, so the chances of finding one in circulation is almost zero. Come on guys, at least educate new members who ask a question as to WHY they are mistaken. Just saying "no" doesn't help them become more educated.
You are, of course, right... Being as this is a somewhat common question, perhaps an addition to the FAQ section would be helpful.
