I have four (4) 1964-D 90% silver Quarter Dollars that I am looking to trade. What I want and need in return are 4 Washington Quarter Dollars that I can use to fill out my album I have been trying to put together for some time now. I am short on expendable income, so I can only trade other wise I would have bought these coins. What I already have is: 1941-D, 1942-S, 1942, 1944, 1954-S (BU, possibly MS-63 candidate), 1957-D, 1958-D, 1961-D, and multiple 1964-D If it isn't on this list, then I need it! I am especially trying to get the 1930's done, so if you can part with ANY of those, that would be helpful! Thanks a ton! --Rob
