United States 1OZ FINE SILVER-ONE DOLLAR

LIBERTY 1906, IN GOD WE TRUST, has a Liberty Lady in a gown holding a bunch of trigs holding her hand out while the sun is setting or rising. the other side of the coin reads . UNITED STATES OF AMERICA. 1 OZ FINE SILVER - ONE DOLLAR............. The writing "1 OZ FINE SILVER - ONE DOLLAR" is stamped around the rim of the bottom of the coin and looks like when it was stamped it then moved a tiny tiny bit to the left and the coin was stamped again thus making a slight stutter of the words, i think its called a double strike....... There is a similar bit with "LIBERTY" wording on the otherside aswell, clearly visible on the 'I" and "B" of LIBERTY. I bought this coin from a coin dealer at a flea market in australia.
