My sister,who knows less than me about coins..and I know hardly anything yet newbie here..cbut she says the mint mark is d over s.. I say she's crazy and it is a D over D.. would someone please check this for us. Also.. is there under the first T in trust. Is In God we trust doubled die? Would you mind to look at the reverse also. The United States of America. Is there anything going on there. My sister says the dime is double stamped. ? Thank you very much..
