Tube of (40) Uncirculated 1956-D Silver Washington Quarters (90% Silver) - This tube contains (40) uncirculated 1956-D silver Washington Quarters, which were struck from 90% silver from 1932 to 1964. These coins are truly in uncirculated condition with a strong mint luster and sharp features. This would be a wonderful investment, as silver is becoming increasingly hard to find and this tube would not take up much room in a safe, storage or safety deposit box.
