I would like to sell my collection of Morgan Silver Dollars. I am havin trouble finding a coin dealer or collector who would like to buy them. I have 7 of them with dates from 1880-1921. Some have mint markings. I have an 1880 with an S mint mark, a 1892 with an O mint mark, a 1904 with an O mint mark and a 1921 with an S mint mark.
